Reporting Crashes

Covered here are APIs relevant to crash reporting for your React Native app.


Privacy Policy

It is highly recommended to mention in your privacy policy that you may be collecting logging data in order to assist with troubleshooting crashes.

There are two ways to have your application report a crash, either automatically or manually. After the crash is sent to your dashboard, you can sort and filter for specific crashes easily.

Automatic Crash Reporting

If you enable Crash Reporting, crashes will automatically be reported to and viewable from the crashes page of your Instabug dashboard.

You'll also see the trends covering the previous 7 days for the percentage of crash-free sessions (sessions that ran and concluded without any fatal errors), the total number of crashing sessions, the total number of sessions, and the total number of unique affected users. You can also see the total number of occurrences, the total number of fatal sessions, the total number of ANRs, the total number of OOMs, and the total number of non-fatal errors. If there is a sharp decline in the crash-free sessions rate, an email will be sent to notify you.


This is the crashes page of the Instabug dashboard.



Crash reporting will not function correctly if the device is connected to Xcode. When it is, Xcode catches all exceptions and they will not be sent to your dashboard.

Manual Crash Reporting

You can manually report your own exceptions or errors in case you already handle them in your code.

Report Exception

To report exceptions manually, use the following method.

try {
      throw new SyntaxError();
    } catch (err) {
      if (err instanceof Error) {


Release Mode

Crashes will only be reported in release mode and not in debug mode.

Crashes List

This section contains a list of all the crashes that have been reported by your application. The title of each crash is usually the most significant line in the stack trace.


An example of the list of crashes in the crashes page of the Instabug dashboard.

Next to each crash in the list, you can find the following details, all of which can be used to sort the crashes:

  • Occurrences: The number of times this crash has occurred and a bar graph representing its occurrences over the past seven days.
  • Users: The number of users affected by this crash.
  • Min ver.: The oldest app version that was affected by this crash.
  • Max ver.: The latest app version that was affected by this crash.
  • Last seen: The last time an occurrence of this crash was reported.

You can then filter for crashes that match any of the following criteria:

  • App version
  • Date
  • Device
  • OS
  • User attributes
  • Type
  • Status
  • Assignee
  • Team
  • Tags
  • Current view
  • Experiments
