Many mobile devs use profilers within IDEs like Android Studio or Xcode to hunt for bottlenecks and automated performance tests to catch performance regressions in their code during development. This is great to do before you ship, but monitoring what’s actually happening on your users’ devices will give you much more observability into the issues they experience (so you can improve them).

Testing an application before it ships is not enough.

To catch the most frustrating performance issues, you need to explore what’s happening on your users’ devices. That means visibility into how fast your app starts, duration of HTTP requests, number of slow and frozen frames, how fast your views are loading, and more.

With Sentry for Mobile, you can now easily monitor your React Native, iOS, and Android app’s performance in real-time without additional setup (or accumulating a pile of testing devices).
