Measuring the success of your indie app can be overwhelming, especially when you're starting out. Focus on these key performance indicators (KPIs) to understand how well your app is performing: user engagement, retention rate, conversion rate, and revenue.

What is User Engagement?

User engagement refers to how frequently users interact with your app. To track this, monitor daily active users (DAU) and monthly active users (MAU). These metrics help you understand how often users are coming back to your app. A healthy DAU/MAU ratio is typically around 20% to 30%.

How Do I Calculate Retention Rate?

Retention rate shows the percentage of users who return to your app after their first visit. Calculating it is straightforward:

  1. Choose a time period (e.g., 30 days).
  2. Count the users who opened your app for the first time during that period.
  3. Count how many of those users returned within the same time frame.
  4. Divide the number of returning users by the total number of first-time users and multiply by 100 to get the percentage.

A good retention rate is around 20% for day one, and a 10% retention rate after 30 days is considered decent.

What is Conversion Rate?

Conversion rate measures how many users take a desired action, like signing up for a subscription. To calculate it:

  1. Count the number of users who completed the desired action.
  2. Divide that number by the total number of visitors.
  3. Multiply by 100 to get the percentage.

A conversion rate of 2% is often seen as a standard for mobile apps, but it may vary significantly based on industry.

How Do I Track Revenue?

For indie developers, tracking revenue recognizes both direct and indirect income:

  • Subscription Revenue: Use RevenueCat to analyze how many users are paying compared to total users.
  • In-App Purchases: Analyze purchase trends to see what users want most.
  • Ad Revenue: If you're using ads, services like Google AdMob will provide detailed insights on ad performance. The ultimate goal is to maximize your average revenue per user (ARPU), which should ideally be at least $1 per month.

Which Metrics Should I Use in Firebase?

If you're using Firebase for tracking app performance, it has built-in analytics that can give you insight into user behavior. Make sure to set up the following:

  • User Engagement Events: Like screen views or button clicks.
  • Attribution Tracking: To know where your users are coming from.
  • Crashlytics: To track app crashes and fix them promptly.

Setting up custom events based on your app's specific goals can refine your data further.

What Are the Common Pitfalls in Tracking Metrics?

Many developers ignore the importance of segmenting their users when looking at metrics. Don’t just look at overall numbers; dive deeper into user demographics and behaviors to find actionable insights. Another common mistake is focusing too much on vanity metrics like download numbers without considering active engagement and monetization.

Next Steps

To really understand how your app is doing, set up a dashboard using tools like Google Analytics or Firebase to monitor these KPIs regularly. Make adjustments based on the data, and focus on improving your key metrics. Tracking these numbers can be the difference between scaling your app and watching it stagnate.
