Reps RPG
A fitness RPG that turns your body into the controller. Real-time AI pose detection counts your pushups, squats and sit-ups as attacks in boss fights — with a pixel-art avatar, elemental weaknesses, leaderboards, and an App-Lock mode that gates TikTok behind a workout.
Turning the boring part
of fitness into a game loop.
Most workout trackers ask you to enter the workout you just did. Reps RPG goes the other way: the workout is the game. ML Kit watches you through the camera, counts each rep, scores your form, and converts that into damage on a pixel-art boss. You don’t open the app to log; you open it to play.
Habit-tracking is a chore.
Fitness apps live and die on motivation. The first week is easy; week three is a graveyard. I wanted a loop the user kept opening because they wanted to, not because they should.
The body is the controller.
Camera-based pose detection turns every rep into an input. Bosses have elemental weaknesses (Fire · Pushups, Air · Squats, Water · Sit-ups) so the user picks the exercise that fits the fight.
A workout you actually want to start.
Now shipping on Google Play with App Lock — the standout feature where addictive apps are gated behind a real squat count. “Do ten squats to unlock TikTok.” Bad habit, gains.
Six systems that
turn workouts into a loop.
Every system serves the same goal: keep the user coming back. Real-time feedback, character growth, and small daily challenges so opening the app feels rewarding before the first rep is counted.
