App Store
An iOS app that uses the phone camera (on-device Apple Vision) to count full push-up reps, matches you live with a random stranger for synchronized duels, and runs a weekly ranked league.
Problem it solves. Provides an automated, objective rep counter plus social competitive motivation to get people to actually do push-ups instead of just tapping a counter or skipping workouts.
Who pays. Fitness-minded smartphone users who want motivation/accountability for bodyweight workouts
Market. Fitness / Health app
How it makes money. $29.99/year subscription with a 7-day trial (promo code giving 3 months free)
The founder is the poster, the app is publicly available on the App Store with an active promo code and the author responds to comments; community feedback treats it as a real launched product rather than obvious self-promo.

“the rep validation is the real product here, not the duels. how does it hold up with a baggy shirt or a dark room? that's where on-device vision counters usually break. does it refuse to count or does it false-count?” ▲ 80
“Pricing seems a bit high for just push-ups, but if you add more stuff interesting concept.” ▲ 40
