A new version of the Android drills has been released.

  • The sound should work on more devices and with lower latency.
  • On devices with a Back button, this button will be intercepted and have the same function as the app Back buttons.
  • Updated user interface elements to keep up with new versions of Android.


If you purchased from QFIT, it should auto-update. If not, use the original install instructions.
If you purchased from GooglePlay or Amazon, I'll upload to them later this week. It should auto-update or you will receive an upgrade notification.

When I'm certain no one is having problems, I'll release the Apple version and move on to updating the Games. Please report any problems quickly.
