Force Touch Test, developed by numbernineteen, is a free Android app that helps users test the pressure sensitivity of their touch screen. The app displays circles on the screen that represent the pressure of the touch, allowing users to test their touch sensitivity by touching the screen softly or strongly. However, the app is only compatible with some devices, and users need to contact the developer through email to check if it works on their device.

The app is categorized under Utilities & Tools and is designed to help users understand their device's touch sensitivity. It is important to note that the app comes with a warning to use it at your own risk, especially when touching the screen with force.
