App Blocker Unlocked by Exercise

In plain English

Blockit locks addictive apps like Instagram and TikTok until the user does real pushups, squats or planks. The phone's own camera checks the exercise with a body-tracking model that runs on the device, so the workout cannot be faked with a timer. Users pay a subscription after a free trial. TrustMRR shows about $500 a month in recurring revenue. The counting happens on the phone, while the owner builds the app and markets it.
