What is crash rate?

Crash rate is the percentage that is calculated by dividing the number of times a user launches an app, by the number of times the app crashed during that same period of time. Usually, this calculation is done on a 24-hour period, so it gives an idea of how well or poor your app is performing in terms of app crashes in a day.

In the modern-day mobile app usage, crash rate can be one of the biggest factors for your users either sticking or abandoning your mobile app. This is the reason why app developers, testing teams and UI/UX designers pay a lot of focus to this element before launching a mobile app.
