HomeBot is a simple, open source Android app that lets you remap the home button long press on your Android device.

You can set different actions to the home button such as:

  • Opening another app
  • Opening a web page
  • Toggling the flashlight
  • Opening the recent apps screen
  • Toggling brightness

The app doesn't need root access but has to be set as your Assistant app in Settings > Apps > Advanced > Default apps > Assist & voice input
