Grindlocker: Earn Screen Time

Lock your addictive apps and earn screen time back with real exercise — push-ups, sit-ups, and squats counted by AI in real time.

Block apps. Unlock with reps.*
Grindlock is built for anyone who knows they scroll too much but can't stop. This app locks down your most distracting apps with Screen Time and makes you earn them back with real exercise. Our AI watches your form through the front camera and counts every rep — no cheating, no honor system.

Accountability that actually works*
Grindlock doesn't guilt-trip you or show you a timer. It makes you move. Pick your apps, pick your exercise, and set the deal: every rep = 2 minutes of scroll time. When your time's up, apps lock again automatically.

AI-powered rep counting*
Your front camera detects your form and counts every push-up, sit-up, and squat in real time. The AI validates each rep so you can't fake it. No manual input. No trust system. Just you vs. the camera.

Screen time you actually earned*
Instead of fighting willpower, you're trading reps for minutes. 10 push-ups = 20 minutes. You set the deal. You earn the time. It hits different when you worked for it.

• AI camera counts push-ups, sit-ups, and squats in real time
