Question: The normal tools we use for error tracking native apps don't really work since the crash reports contain minified js. The tools we use for web apps don't seem to support react native. Are there services that do support react native and if not do we have any other options to get useful crash reports?

Answer: 
[TL/DR]

We created a react-native-bugsnag lib before the official bugsnag lib was out, but it's now deprecated. 

Use the official instead.

[Long version]

~~We were also looking for a way to report errors on react-native and since I was not really happy with the existing solutions I found (Crashlytics, and sentry), me and Joshua Pinter decided to write our own implementation of a react-native module, that works with bugsnag.~~

Here it is: [react-native-bugsnag](https://www.npmjs.com/package/react-native-bugsnag).

It supports both **iOS/Java and Javascript** handled and unhanded crash reporting.

I hope you enjoy!
Bug snag - <https://docs.bugsnag.com/platforms/react-native/react-native/> 
Crashlytics - <https://www.npmjs.com/package/@react-native-firebase/crashlytics> 

This are tools used for React native to report bugs. Hope it helps ! Thank you
