# ARCore debugging

For your ARCore app deployed on Android, you can use the following utilities to
help with debugging:

- [Call logging](https://developers.google.com/ar/develop/debugging/call-logging) - ARCore API calls logged
  to the Android device log help troubleshoot runtime behavior and performance
  issues in your app.

- [Performance overlay](https://developers.google.com/ar/develop/debugging/performance-overlay) - ARCore
  can provide a real-time overview of an app's performance with statistics
  on CPU, memory, and other system resource usage in an overlay that displays
  on the app. The performance overlay also provides a CPU usage breakdown for
  individual ARCore features.
