iPhone
Block your most distracting apps. The only way back in is push-ups or squats, counted live by your camera.
You can't press ignore on a push-up... or a squat.
Kro blocks your most distracting apps. The only way back in: push-ups or squats, counted live by your camera. No reps, no scroll.
Every blocker has a back door: a "15 more minutes" button, a settings toggle, an honor-system check-in. You found it by day three. Kro's only back door is on the floor.
HOW IT WORKS
• Pick the apps that eat your nights and set a daily budget
• Spend it, then Kro asks for reps before letting you back in
• Your camera counts push-ups or squats, on-device. Half reps don't count.
• Finish the set, earn your minutes. Out of time? Back to the floor.
HARDCORE MODE
Every day starts at 0 minutes. Nothing is free. Every scroll is earned.
WHAT ACTUALLY CHANGES
The "just 5 minutes" that ends at 2 a.m. now costs a set of push-ups. Half the time you'll decide the scroll isn't worth it, that's the point. The other half, you're getting stronger by accident.
You don't need more willpower. You need a door that only opens for reps.
PRIVATE BY DESIGN
Reps are counted on your device. No video ever leaves your phone.
Kro is free to try. After the trial, a subscription is required to keep blocking apps and earning screen time.
