Crash-Free User Metrics
When you add the Firebase Crash Reporting SDK to your app, you can see the the percentage of users that have not encountered errors in your app over the selected timeframe, shown in the Error-free users panel of the Crash Reporting console.
This panel displays:
- The percentage of users who are free of both fatal and non-fatal errors for iOS and Android apps
- The percentage of users who are free of fatal errors for C++ apps
These metrics help you to monitor the health of your app releases and the effectiveness of recent improvements to your app.
The Error-free users metrics are generated based on data provided by the the Crash Reporting SDK. So, this metric includes data for all users, but only for app versions where the Crash Reporting SDK is enabled.
