15 Key Metrics to Track for Measuring Success and User Engagement of Your New Mobile App
Tracking the right metrics is crucial for understanding how users engage with your mobile app and measuring its success beyond just download numbers. The following 15 essential KPIs will help you gain actionable insights to optimize user experience, boost retention, and drive growth.
1. Daily Active Users (DAU) & Monthly Active Users (MAU)
Importance: DAU and MAU reveal the size of your actively engaged audience daily and monthly. The DAU/MAU ratio (stickiness) indicates how frequently users return to your app.
How to Use: Monitor the DAU/MAU ratio to gauge user loyalty. A higher ratio means stronger daily engagement, a leading indicator of app “stickiness.” Learn more about DAU and MAU.
2. User Retention Rate
Importance: Retention rate measures the percentage of users returning after their first app session, crucial to understanding long-term engagement.
How to Use: Track cohorts (Day 1, Day 7, Day 30 retention) to spot drop-offs and improve onboarding or user experience. Tools like Firebase Retention Analytics can help.
3. Churn Rate
Importance: Churn rate tracks users who stop using your app within a specific period and is the inverse of retention.
How to Use: Analyze churn by user segments or acquisition channels to identify and target disengaged users with re-engagement campaigns. Learn more about reducing churn here.
4. Session Length
Importance: Session length measures the average time users spend per app visit. Longer sessions typically reflect higher engagement.
How to Use: Monitor changes in average session duration to detect usability issues or content attractiveness. See how to analyze session length with Mixpanel.
5. Session Frequency (Interval)
Importance: This metric tracks how often users open the app, indicating habitual use.
How to Use: Frequent sessions imply your app is integral to users’ daily routines. If frequency drops, consider push notifications or personalized engagement strategies.
6. User Acquisition Cost (UAC) / Cost Per Install (CPI)
Importance: CPI measures the expense to acquire a user. Efficient acquisition means paying less per install while maintaining quality users.
How to Use: Integrate marketing platform data to calculate CPI and correlate with retention to ensure cost-effectiveness. Find strategies to optimize CPI here.
7. Lifetime Value (LTV)
Importance: LTV estimates the total revenue generated by a user over their app usage lifetime, guiding marketing budgets and monetization strategies.
How to Use: Compare LTV with CPI to ensure profitability. Boost LTV by enhancing retention and expanding in-app purchases or subscriptions.
8. Conversion Rate
Importance: Tracks the percentage of users completing key actions such as registrations, purchases, or upgrades.
How to Use: Identify where users drop off in your funnel and run A/B tests to improve conversion rates. Explore conversion optimization techniques here.
9. Revenue Metrics (Daily/Monthly Revenue)
Importance: Knowing revenue over time helps assess financial performance and growth trends.
How to Use: Correlate revenue spikes with marketing efforts or feature launches to evaluate impact and plan future campaigns.
10. Number of Sessions per User
Importance: This indicates how often an individual user launches your app within a period.
How to Use: Use this alongside session length to determine if users prefer frequent short visits or infrequent longer ones, then tailor engagement efforts accordingly.
11. Feature Usage Rate
Importance: Understanding which features users engage with most helps prioritize development and identify underused functionality.
How to Use: Track feature adoption with product analytics tools to optimize user flows and improve or retire underperforming features. Tools like Amplitude Feature Analytics are helpful.
12. Crash Rate & Bug Reports
Importance: High crash rates degrade user experience and increase churn.
How to Use: Use crash reporting tools such as Sentry or Crashlytics for real-time monitoring and resolve issues promptly.
13. Net Promoter Score (NPS)
Importance: NPS gauges user satisfaction and willingness to recommend your app, driving organic growth.
How to Use: Collect NPS via in-app surveys regularly and address concerns from detractors to enhance user experience.
14. App Store Ratings and Reviews
Importance: These influence app discoverability and provide user sentiment feedback.
How to Use: Monitor trends in ratings and reviews to inform product updates and customer support strategies. Tools like AppFollow help automate this process.
15. Uninstall Rate
Importance: High uninstall rates can signal dissatisfaction or unmet expectations.
How to Use: Analyze when and why users uninstall your app, combining uninstall data with retention and session metrics to address root causes.
Integrating Metrics for Comprehensive Insights
Combine these KPIs for deeper understanding:
- Link retention and feature usage to identify which features promote ongoing engagement.
