Top App Performance Metrics To Monitor Image

Even the most thoughtfully developed apps will need to evolve, and one effective way to spot opportunities for improvement is through application performance monitoring.

Application performance metrics fall into several categories, each providing a unique look at app performance and areas for improvement. We believe it’s essential to be keeping an eye on user acquisition, user engagement, and customer satisfaction.

  • User acquisition metrics reveal the success of your marketing efforts, monitoring things like the number of downloads and users.
  • Engagement looks at user experience and how users interact with the app, from how long the average person spends in the app to user turnover rates.
  • Customer satisfaction measures how successfully an app meets user expectations and the likelihood of a user recommending the app.

We’ll look at each of these app performance categories and talk about key metrics to gauge how your app is doing in each of them.

App Performance Metrics for User Acquisition

User Acquisition Metrics

App performance metrics related to user acquisition provide valuable insight to help you focus your marketing budget and tap into new customer bases. Acquisition metrics range from app store rankings to insights on how users became aware of your app. Services like, APPLyzer, and Adjust can help you monitor app acquisition metrics.

App Store Ranking

A primary acquisition metric is app store ranking. Ranking refers to the visibility of an app when a user searches for it in the app store. A high ranking means an app appears within the top search results. App ranking is increased through optimized keywords, positive user reviews, and regular updates. Ranking matters most for iOS apps because Apple uses a search algorithm that places higher-ranked apps first.

Number of Downloads

Number of downloads represents another critical acquisition metric. This measurement links directly with the extent of app reach. As it sounds, the number of downloads tracks how many mobile app users install an app onto their device. Low numbers of installations could mean that marketing campaigns need to be further tailored or that the app could use an upgrade.

App Attribution

It’s also helpful to track the sources that lead users to discover your app, a metric called app attribution. Attribution provides a glimpse at the success of marketing efforts by enabling you to know what sites or promotions generated higher click-through rates and downloads.


One additional metric we like, viralness, reveals the number of new users brought in by a typical current user. This is a handy metric for many social consumer apps. You have a lower cost per acquisition if you gather new users from viral sharing rather than through direct marketing. Viral acquisitions also tend to engage more because they interact with friends and family vested in the app. In-app promotions that reward current users for referrals can help increase viral reach.

App Performance Metrics for User Engagement

User Engagement Metrics

User engagement metrics measure the value customers get when using an app. These performance metrics are worth tracking for most types of apps. The data provides information about the activity level of consumers and flags potential pain points. Tracking user engagement metrics can help developers view user behavior patterns and improve an app’s usability. Tools to track user engagement metrics include Google Analytics, Mixpanel, and Firebase.

Active Users

Time factors heavily into user engagement and helps measure customers’ activity levels. Metrics for user engagement include daily, weekly, and monthly active users (DAU, WAU, MAU), which gauge the number of users within a time period. “Active” can mean anything from opening the app to posting and engaging with content. However, app experts tend to look at the DAU ratio to MAU (“stickiness”) rather than the individual metrics. This ratio shows the number of days in a month that users return to the app and provides a more accurate look at active users.

Retention Rate

Retention, one of the most important app performance metrics, shows how many users return to the app at least one time. The metric is often evaluated at 30, 60, and 90 days. While good retention rates vary by industry, it’s obvious that the higher the number, the better. It’s a strong indicator that users value the app. In another post, we discuss how to keep users engaged with your app.

Churn Rate

Churn rate offers the opposite performance metric to retention: the percentage of discontinued users. Understanding when users churn in the lifecycle is critical to addressing potential engagement problems. If users churn soon after installation, the app might have technical problems like frequent crashes, an unfixed bug, or other application errors. Losing long-term users can indicate that the app provides only short-term value or doesn’t meet expectations.

Visits & Views

Both average visit time and screen views per visit are also useful application metrics to evaluate end-user experience. Average visit time shows how long users engage with the app in one visit, while screen views per visit records the number of screens clicked in a session.


Session length is a good indicator of your app’s engagement. Generally, the more time a user spends on the app, the better, but you may also want to look at session length in terms of the number of app crashes and uninstalls and see if there is a correlation. Session depth reveals how far along the user path someone travels before closing the app; for example, going from browsing to making an app purchase may correlate with greater session depth than logging in to check for content updates. Likewise, app session interval, which measures the period of time between two consecutive sessions, offers additional insight, enabling you to measure how attached users are to your app.

App Performance Metrics for Customer Satisfaction

Customer Satisfaction Metrics

The final category of app performance metrics deals with customer satisfaction, which shows consumer preferences and expectations. User satisfaction metrics include user ratings and reviews, in-app feedback, and satisfaction surveys. Examining these metrics can provide a deeper understanding of what customers want from your app and allow app developers to hone features and in-app support to better meet user needs. Appbot, appFigures, and Lookback all provide app metrics on customer satisfaction.

Reviews & Ratings

Reviews and ratings can provide incredible, actionable insights to your business about what additional features and improvements would be valuable. They also have significant power to influence acquisition. App store reviews affect app store ranking, so maintaining a positive score improves the visibility of an app. According to Apptentive’s “Mobile App Ratings and Reviews” guide, peer recommendations in the form of app store ratings and reviews stand alone as the single greatest driver of discovery and conversion.

In-App Feedback

Collecting in-app feedback about bugs and usability problems can often help avert negative public posts by allowing you to quickly fix any issues. Feedback can be gathered via chat systems, email contact forms, and surveys. In-app feedback reaches customers actively using the app and requires no outside windows or web browsers, streamlining the process for users. A particular type of in-app feedback, rating metrics, can complement customer reviews. If an app user provides a positive rating, you can prompt them to leave an app store review, helping your ranking.

Final Thoughts

These highlighted app performance metrics only scratch the surface of the quantitative and qualitative data you can gather about an app. With the overwhelming number of mobile app metrics you can track, picking and choosing the critical metrics for your app can prove challenging.

Unlock the Possibilities of Apple‘s Custom Product Pages

There’s a feature in the Apple mobile ecosystem that can dramatically enhance how you market your app. Custom product pages allow you to segment your digital products in ways that will increase conversions and revenue. You can tailor your landing pages and create custom search ad campaigns that match customer demographics. The App Store hosts over 2 million apps, and users have short attention spans. Employing custom product pages can ensure a uniform and uninterrupted journey for users throughout their acquisition experience—from Apple Search Ads to the App Store. With the right approach, custom product pages can be a game-changer for your app’s success. How can you get the most out of custom product pages with a new or existing app? If you aren‘t currently using custom product pages, now is a great time to implement them to gain an edge over your competition. Beyond user targeting, you can promote a seasonal event, showcase culturally relevant content, and more. What are Apple custom product pages (CPPs)? Every app on the App Store has a product page, also known as an app store listing. Beyond this main page, Apple‘s custom product pages enable you to customize the look and feel of your Apple product for specific audience segments, keywords, or promotions. With Apple’s custom product pages, you can design up to 35 different versions of your app’s store listing. You can use these variations to optimize search ad campaigns and promote unique listings through shareable URLs. Key Features Customization: You can change ‌three assets on the variations of your product page: screenshots, app previews, and promotional text. Discoverability: You can optimize each page using specific keywords for search and messaging that expands your reach. Localizability: You can use different languages, so custom pages reach audiences in multiple countries. Control: You can use the App Store Connect API to make changes across multiple custom pages simultaneously. Android vs. iOS Apple has always been known for its strict control over the user experience of iOS apps. Apple custom product pages enable greater control and creativity to market your app. While Google’s Play Store provides more flexibility through its custom store listings, Apple is catching up with custom product pages. Here, we’re focusing on Apple‘s feature set, but the benefits and best practices apply across platforms. Benefits of Custom Product Pages Improved App Marketing Metrics Custom product pages are crucial in conversion rate optimization (CRO) and app store optimization (ASO). Custom pages can help you to: Increase CRO: By tailoring your messaging and visual design to your target audience, you’ll increase the likelihood that users will download your app. Improve ASO: Multiple versions of your store listing can capture more promotional traffic and improve keyword and engagement metrics. With the right strategy, customer product pages can significantly boost user acquisition and marketing ROI. Targeted Search Ads Custom product pages in Apple’s App Store and Search Ads allow for different ad variations and strategic campaigns targeting different types of users. These features help potential customers better understand the app before downloading it. For instance, the app Mountain Climber can run separate ads targeting cyclists, hikers, and rock climbing enthusiasts. Based on the URL clicked, those ads drive potential users to three tailored custom product pages for the same app. You’re increasing the chances of app conversions by corresponding the custom App Store page with the ad creative that attracted the customer in the first place. Tailored Testing It’s important to note that custom product pages won’t appear in organic search results on the App Store. Of course, the organic experience is still important, and you can improve it using Apple features for testing tailored to your marketing goals. Split Testing Through Product Optimization Using Apple’s product page optimization feature, you can perform split tests on up to three distinct “treatments” of your default page. However, the elements you can adjust are limited to visuals—app icon, preview video, and screenshots. After determining the most successful treatment, you can apply it to your app’s default page, ensuring all users receive the most impactful organic search result. Variable Testing With Custom Pages While Apple‘s split testing tool for product page optimization has benefits, custom product pages may offer a more reliable approach to testing theories about your app page. By designing multiple custom pages with unique designs or copy, you can evaluate which version performs better in engagement metrics, conversion rates, and return on investment. You can then apply those learnings to improve your organic default page. Creating a Custom Apple Product Page Apple provides a detailed technical guide when you are ready to configure your product pages. Before taking that leap, consider the following insights to guide your efforts to success. Identify Your Target Audiences Designing effective pages that resonate with multiple target audiences requires a deep understanding of each audience’s specific needs and preferences. For example, a TikTok user’s preferences will vary based on specific demographics like age. You’ll want to learn those preferences in depth to get the most out of any customized versions of these landing pages. Before embarking on a custom product page project, researching your target audiences is an obvious first step. You can effectively focus your efforts where they’ll have the most impact through user surveys, testing, and analysis. Surveys User surveys can help you gather feedback and insights from your target audience on their needs, preferences, and pain points. You can use online survey tools like SurveyMonkey or Google Forms to create and distribute surveys to your target audience. Testing User testing involves observing users as they interact with your app to identify areas of improvement and gather feedback. You can use remote user testing tools like UserTesting or Userlytics to conduct user testing sessions with your target audience. Analysis App Store analytics can provide valuable insights into your target audience’s behavior and preferences. By analyzing App Store data such as user reviews, ratings, and search queries, you can better understand your audience‘s needs and preferences. Impact Creating multiple versions of your app page can be time-consuming and may require additional resources. Consider focusing your efforts on your most valuable audience segments, where you can maximize the impact of your custom product pages while minimizing the resources required to create them. Choose Strategic App Previews & Screenshots The key benefit of custom product pages is the ability to segment what each user sees when they preview your app. Here are some tips to choose assets that will attract and convert your target user. Emphasize features: Use your media to highlight your app’s key features and benefits. Targeted images and videos can catch the attention of different user segments. Keep it concise: Use short video clips and images. Quickly and effectively communicate your app’s target value proposition to each of your audiences. For instance, let’s consider a “Fitness Tracker” app targeting two user types: gym enthusiasts and busy professionals. For the gym enthusiast audience, you can use app previews to show users how to set up and customize their workout plans, track their progress, and view their stats and achievements. For the busy professional audience, you can use screenshots to showcase the app’s meal planning and nutrition features. For either audience, users can see firsthand how the app can help them achieve their fitness goals at first glance. Provide Relevant Content & Keywords in Promotional Text Content about your app and relevant keywords in the promotional text help you attract the right users and increase conversions. For example, if you’re developing three custom product pages for a healthcare app—one for patients, one for doctors and clinicians, and one for health organizations—here is how the promotional text and keywords might vary per page. Custom Page for Patients Promotional Text: Take control of your health with our intuitive healthcare app Access personalized health information and track your progress Connect with healthcare professionals and schedule appointments easily Keywords: Healthcare app, personalized health information, track health progress, connect with healthcare professionals, schedule appointments Custom Page for Doctors & Clinicians Promotional Text: Streamline your practice with our advanced healthcare app Efficiently manage patient records and appointments Access medical resources and collaborate with colleagues Keywords: Advanced healthcare app, practice management, patient records, appointments management, medical resources, collaboration tools for doctors Custom Page for Health Organizations Promotional Text: Transform your healthcare organization with our comprehensive app Improve patient outcomes and streamline operations Gain insights through data analytics and reporting tools Keywords: Comprehensive healthcare app, patient outcomes, streamline operations, data analytics, reporting tools, health organization management Measure & Optimize After your customized product pages go live, you can gauge their effectiveness using App Analytics in App Store Connect. You can track product page impressions, downloads, re-downloads, and conversion rates to assess how well each page motivates app downloads. You can also measure retention and the average proceeds per paying user for each custom product page. Another way to gain insights is to compare your custom product pages to your default. Doing so lets you determine whether users who downloaded your app through a custom product page tend to stay engaged longer or spend more on in-app purchases. This information can help you make informed decisions on how to optimize your app‘s marketing strategy. Promoting Your Custom Product Page Reach Broader Audiences With Distributed Campaigns After developing a custom product page, you can share it through your promotional communications and marketing efforts with its distinct URL. Your app‘s marketing channels might include email marketing, social media, digital advertising, influencer programs, and promotions—the possibilities are endless. For instance, an app that caters to sports enthusiasts might showcase the latest Superbowl champions in an email promotion and connect to the tailor-made product page that spotlights that team. The exclusive URL incorporates a new product page ID parameter into the standard product page URL. Increase Impressions With Apple Search Ads Apple Search Ads enable you to produce ad variations for App Store Today tabs and search results for eligible custom product pages. When you establish your ads campaign, you can customize your ad message and visuals for different audiences, product launches, or seasonal promotions. Tailored product pages can greatly enhance the effectiveness of Apple Search Ads and thereby increase the ROI of your paid campaigns. Giving users a more relevant and individualized experience boosts the conversion rate of keywords and reduces the cost per install. Ultimately, you‘ll obtain more downloads—while paying less for each. Promote Events for Maximum Exposure Certain seasons, holidays, and events present great opportunities for increasing downloads. To capitalize on these moments, you can create custom product pages that showcase them. These pages can be tailored to highlight relevant features, promotions, or content related to the specific occasion, making your app more appealing to visitors. There has been a lot of excitement around in-app events, as well. Adding to the iOS marketing arsenal are these timely in-app experiences, such as challenges, competitions, or special content launches, featured on your product page. In-app events have unique promotional capabilities and App Store discoverability. Notably, all visitors to the custom or default product page will see the same in-app events. Understanding the diverse needs and motivations of your target audience can help in tailoring your marketing approach accordingly. These are just a few examples of how in-app events and custom product pages can be used together strategically: Engage existing users: You can re-engage existing customers through a pairing that piques their interest and encourages further engagement. For example, a user-targeted custom product page alongside an in-app event challenge. Attract new users: You can target an untapped demographic by marketing specific promotions that expand reach. For example, a seasonal custom product page alongside a special in-app event featuring new holiday releases. Whether for seasonal promotions alone or combined with in-app events, the specific implementation of custom product pages is in your hands. It’s important to adapt to your unique business context, promotional timelines, creative assets, and advertising approach to ensure success. Final Thoughts Improving Conversion Rates With Custom Product Pages Custom product pages offer powerful freedom and flexibility, allowing you to segment your digital products in ways that boost conversions and increase revenue. You can use custom product pages to engage with users at any level and tailor your approach to your specific marketing goals. With the fast-paced and competitive app landscape, innovating and adapting are crucial. By embracing the power of custom product pages, you can stand out from the crowd, captivate your target audience, and achieve significant growth for your app. List of Additional Resources For implementation support, Apple’s developer site has a step-by-step technical breakdown to configure multiple product page versions.

Developing Apps for Generation X

Generation X has become an important demographic for businesses and app developers alike. They have a higher spending power compared to younger generations. Gen Xers are known to be independent, resourceful, and pros at maintaining a work-life balance. This generation has a strong desire for convenience and efficiency in their daily lives. To successfully develop apps for Generation X, developers should consider the unique needs and preferences of this age group. This includes creating intuitive interfaces, prioritizing data transparency, and offering real-time solutions. To stay ahead, businesses have to leverage their greatest tool—intuitive features that hit the mark. What We Know About Generation X Born between 1965-1977, Gen X makes up the smallest generation. They grew up with little to no supervision and lots of independence. This generation spent much of their youth exploring brilliant cinema like Star Wars, video games like Atari, and the premiere of MTV. As a result, they have a special relationship with pop culture that remains unique to this generation. Gen X witnessed the rise of personal computers, video games, and other technological advancements. They were the first generation to grow up with home computers and video game consoles. Ever-evolving technology advances allowed Generation X to be connected like never before. More than a whopping 80% of Gen Xers report that they are online daily. In terms of social media, they gravitate to platforms like Facebook, Twitter, YouTube, Reddit, and Instagram. Many are surprised to hear that Gen Xers spend about 2 ½ hours on phone screens daily—that’s less app time than younger generations, but still significant in terms of hours of screen time. Generation X has strong brand loyalty and will be lifelong users of products they feel add real value to their lives. Although initially skeptical, once they’re hooked, they’re hooked. Gen X grew up during a time of change and uncertainty. Their experiences shaped their attitudes and values, including their focus on independence, self-sufficiency, and resilience. They look to apps that fulfill a specific purpose and provide meaningful value in their lives. How Gen X Uses Technology Differently Gen X is a generation that values efficiency, productivity, and simplicity. Collectively, Gen Xers are known to be independent and resourceful individuals. They tend to mistrust large corporations and are often skeptical at first. But once you earn their trust, you’ll find this generation to be exceedingly loyal. Gen Xers bring a critical component to the table and the economy at large—a wealth of experience. Because of their years in the workforce, they have a lot of purchasing power. Additionally, Gen X has very specific circumstances and interests unique to their collective experience. Parenting, health, travel, and lifestyle are often at the forefront of their minds. The people in this generation tend to be collaborative, experienced, and hard-working, which makes for strong leaders. That said, they are less likely to casually browse their smartphones like their younger counterparts. In terms of phone surfing habits, Gen X is a pragmatic generation and tends to use technology for practical purposes, such as communication, productivity, and entertainment. They are less likely to use social media for personal creative expression and more likely to use it for networking and professional purposes. They prioritize privacy and security and are more concerned about data privacy than other generations. App developers need to specifically address a need and create apps that reflect their browsing habits. They will need to develop feature-specific apps that solve problems and offer real convenience to users. Attracting the Elusive Gen X When Developing Your App Smarter, Not Harder Gen X is managing a heavy load and holding down the fort. Make their lives easier by streamlining their tasks and creating solutions to accomplish their everyday undertakings. While Millennials value convenience, Gen X values practicality. Gen Xers aren’t married to their work and appreciate a positive work-life balance with time away from work. They also appreciate disconnecting from their phone at times to avoid being constantly occupied online. Consider incorporating features such as notifications, “time limits,” or project tracking to make the app useful for their work and personal lives. Example: Pomodoro Method Take Asana’s Pomodoro app, for instance. Pomodoro is a time management method that uses a timer to break down work into intervals, split into short breaks. The PomoDone app helps people boost their productivity with scientifically proven timeboxing and Pomodoro techniques on top of Asana’s project management features. A win, win app with a killer benefit for the busy Gen X generation. Informed Transparency around sensitive information is important for Gen Xers. With increasing cybercrime and digital literacy, Gen X users are concerned about security threats online. Be sure to communicate with direct notifications and be explicit about what their data will and won’t be used for. Gen Xers are natural skeptics of unfamiliar brands. Rightfully so, as they’re also parents looking to keep their kids safe. It’s important to keep Gen X users in the know and in control of the way their data is used. Example: Customizable Privacy Tools Google manages customers’ data quite brilliantly by putting the user in the driver’s seat. Google offers customers controllable and customizable privacy tools so that the user can keep constant tabs on their privacy settings. Combine Real-Life Value With Real-Life Solutions While Millennials intrinsically value being connected, Gen X values “real life” experiences. This generation spent decades without technology, growing up in a tumultuous time in which they were mostly on their own. This generation is known to have the greatest brand loyalty and will be lifelong users of products they feel add *real* value to their *real* life. Consider anticipating the solution and providing the content they seek before they ask for it. Evaluate how your product can anticipate Gen X users’ needs. Shine a light before Gen Xers even enter the room. Example: Smart Technology Take Apple HomeKit, smart switches that turn on and off, open and close, with the snap of your fingers—or rather, your voice. Apple’s broad ecosystem offers powerful smart home controls, features, and monitoring, including a smart lock, smart lights, and much more. Whether you want to optimize your lighting to your preferences, grow a small indoor garden, or are just plain tired of carrying keys, smart tech has you covered. Let Your Solutions Shine Known as the “worker generation,” they’ve gathered years of invaluable work experience. Gen Xers are busy. They’re tackling matters like homeownership and child care and are reaching the heights of their careers. Save your product from their frustration and know that a straightforward approach is your best bet. Think less ornamentation and more functionality. Lose those few sentences of the fluffy copy. Ditch the long animations and unnecessary time. Create a simple, practical design; a good user experience connects Gen Zers to your product’s valuable solution as quickly as possible. Build an app that’s designed with a familiar UX for Generation X users, such as buttons, checkboxes, and dropdown menus. Avoid trendy design elements that may be confusing or distracting, allowing for your technology to shine. Example: Innovation & Impact For example, with the Cancer Exercise app, we collaborated with our client to create the first mobile exercise app for iOS designed specifically for cancer survivors. The innovation lies within the solution created by our client, Anna L. Schwartz, Ph.D., FNP-BC, FAAN, who is a world-renowned pioneer in cancer research. The app provides individual exercise prescriptions through a custom exercise program tailored based on daily fatigue, current treatment, treatment type, and more. The app is innovative, straightforward, and impactful—and brings great value to their target audience. Respect the Values & Identities of Every Generation Gen Xers bring a critical component to the table and economy at large: a wealth of experience. Although this generation is sometimes overlooked, they’re responsible, resourceful, and loyal once they believe in the technology and brand they’re consuming. Developing and addressing Gen Xers will prove to be beneficial in scaling your app’s success. You’ll attract pragmatic customers that will stay loyal to your brand through and through. Every person is unique in how they relate to technology and the world around them. At the same time, there are similarities between generations and how they use technology. Deeply understanding your audience and market is an important prerequisite to developing a successful app. Respecting the values and identities of every generation is key to developing apps that will resonate with your target audience.
