Did you know that the average mobile app loses 90% of its active users within the first three months? That might not be encouraging data, but what works here is continuous improvement and adaptation. But how do you know how your app is performing, how users are interacting with it, and whether it caters to their preferences and needs? In such a situation, Key Performance Indicators (KPIs) turn out to be the best way to measure the app's performance based on several aspects. 

However, the biggest challenge persists in choosing the right KPI to track. If a single step goes wrong, you may miss an opportunity to enhance your app’s effectiveness. There is no dearth of KPIs available for tracking mobile app performance, and this abundance of options gives nothing but confusion. Remember, tracking the wrong KPI may waste your resources and lead to losing sight of your goals. 

So, to help you choose the best KPI for your mobile app, we have created a list of the top 30 app KPIs from the three most crucial categories: App engagement, User experience (UX), and performance and Revenue. So, let’s get started!

What are Mobile App KPIs?

Key Performance Indicators (KPIs) are crucial metrics that measure the effectiveness and performance of a mobile app. They assist in monitoring the achievement of particular objectives and in enhancing user interaction.

The KPIs to focus on are determined by the nature of your application. For instance, for a gaming application, you would be interested in KPIs such as the number of users who are active daily and the average income generated per user.

On the other hand, if your application is centered around social media, you would place more emphasis on KPIs like the total count of subscribers and the number of times content is shared socially.

What Makes KPIs Important for Mobile Apps?

The mobile app industry is fiercely competitive, with over 257 billion apps being downloaded in 2023. Monitoring the appropriate Key Performance Indicators (KPIs) can help you expand your business and differentiate yourself from competitors.

Here’s how measuring KPI for mobile apps is essential for your business:

Top 30 KPIs for Measuring Mobile App Performance and Growth

To help our readers in choosing the right KPIs for their mobile app, we have divided them into three key categories: 

  • App engagement KPIs
  • User experience (UX) and performance KPIs
  • Revenue KPIs

App Engagement KPIs

App engagement KPIs allow you to monitor the key metrics to understand user interaction with your app and pinpoint areas that need enhancement:

1. Daily Active Users (DAU)

DAU is a KPI that measures the distinct users interacting with your app daily. This metric is instrumental in assessing your app's daily usage and expansion.

Calculation method:

DAU = Number of unique users who use your app within a 24-hour period

2. Monthly Active Users (MAU)

MAU measures the distinct users who interact with your app each month. This metric is useful in evaluating your app's monthly growth.

Calculation method:

MAU = Number of users who engage with your app within a 30-day period 

3. Stickiness Ratio

The stickiness ratio or the user retention index provides insight into your app's "stickiness" by quantifying the frequency of users returning to your app. A high ratio signifies high engagement rates, with a larger proportion of daily users.

Calculation method:

Stickiness ratio = DAU / MAU

4. Session Length

Session length is the duration a user spends on your app from the moment they open it until they close it. This metric can help ascertain if users remain on your app long enough to complete a desired action. Apps like Facebook and Instagram excel in this KPI, with an average user spending 55 minutes per day on these apps.


Calculation method:

Average session length = Total session length / Number of sessions

5. Screens Per Session

Views per session measures the average number of views your users have in a single session. It can suggest whether users find your app engaging enough to explore more.

Calculation method:

Screens per session = Total screen views / Total sessions

6. User Retention Rate 

User retention rate monitors the number of users who revisit your app after downloading it. A high retention rate suggests that users are finding value in your app.

Calculation method:

Retention rate = (Monthly active users / Total app installs) x 100

7. Churn Rate

The churn rate is a crucial metric as it quantifies the percentage of users who discontinue using your app. A high UAR could signal issues like poor user fit or deficient features.

Calculation method:


Churn rate = (Lost users / Users at the beginning of a period) x 100

8. Abandonment Rate (AR)

Statistics reveal that 25% of apps are only used once after downloading. The app abandonment rate differs from the retention and attrition rate. This metric quantifies the number of users who download and install your app but don't complete the signup process.

Calculation method:

Abandonment rate = (Users who stop using the app / Total number of app users) x 100

9. In-App Actions (IAA)

The in-app action rate refers to the number of actions users perform within your app. Examples can include liking a post, making a purchase, or watching a video.

Calculation method:

In-app actions = Number of users who complete a desired action / Total number of users

10. Push Notification Engagement

Push notifications are potent tools that can enhance user engagement. Push notification engagement rate quantifies the percentage of users who engage with your notifications.

Calculation method:

Push notification engagement = (Number of users who interacted with a push notification / Number of push notifications sent ) x 100
