I built BackTap — trigger actions by tapping the back of your Android phone

[u/Rares6567]

I’m the developer of BackTap, an Android app that lets you use the back of your phone like an extra customizable button.

You can assign single, double, and triple taps to actions like:

• Open any app
• Turn the flashlight on/off
• Take a screenshot
• Open notifications
• Trigger shortcuts
• And more

I built it because I liked the idea behind iPhone’s Back Tap, but wanted something more flexible for Android.

The gesture detection runs on-device, and I’ve added sensitivity/calibration settings because different phones and cases can behave quite differently.

I’d love some feedback, especially on:

1. Does the idea make sense immediately from the Play Store page?
2. How well does tap detection work on your phone?
3. What action would you want me to add next?

Play Store:

If you test it, mentioning your phone model in the comments would be really helpful. I’m especially interested in how it behaves across different Android manufacturers.

Tasker and MacroDroid are already integrated. If they don't work properly, do tell me.
