Haptic Feedback Checker is a free Android application developed by JANE PROJECT that helps Android developers implement haptic feedback in their applications. This app is designed to assist developers who are using HapticFeedbackConstants but do not know how to vibrate their device. Haptic Feedback Checker is not available on Google Play, so it must be downloaded from a third-party source.

The app is recommended for Android devices up to version 8.0 and Pixel smartphones such as Pixel2 and Pixel 5a. The Haptic Feedback Checker is an excellent tool for developers who want to ensure that their applications have haptic feedback and want to test it before releasing their apps to the public.
