Questions you probably have
What if I get an important call?
Calls are never blocked — incoming and outgoing. You can always make and receive phone calls, even during a workout.
Can I cheat it?
The front camera uses AI to verify every rep. You can’t just wave your arms or set the phone down. It counts real squats, real push-ups, real lunges, real sit-ups.
What if there’s a real emergency?
There’s a backup password you can set. Use it to unlock instantly. But most people never need it — because the workout only takes 4 minutes.
Is my camera data safe?
100%. All camera processing happens on your device. No video is recorded. No data is uploaded. No internet is required. The app works fully offline.
How hard is the workout?
You choose the difficulty level. Start easy, build up. The minimum session is about 4 minutes — shorter than the time most people spend deciding what to watch on Netflix.
Why do I need to join a Google Group to download?
The app is in early access testing on Google Play. The group is how Google lets us give you the test build. It takes about 60 seconds and you only do it once.
Ready to earn your phone back?
60 seconds to sign up. 4 minutes to work out. A lifetime of excuses if you don’t start now.
