### Platform(s)

- iOS

I haven't checked on Android

### Current Behavior

When Haptics.vibrate is called too often, especially while the previous calls haven't been finished yet, the phone will hang.

### Expected Behavior

The haptics are triggered from a different thread than the main one so we don't block the app completely when doing trivial actions.

### Other Technical Details

As stated per the documentation, https://developer.apple.com/documentation/corehaptics/preparing_your_app_to_play_haptics/#3200019, core haptics is thread safe so it can be called from wherever without impact.
