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.

Most ab routines treat your core as one muscle. It is not. Upper abs, lower abs, obliques and deep core develop at different rates, and the weakest one caps how the whole set looks. AbForge finds that zone and builds around it. HOW IT WORKS Take one photo of your abdomen. AbForge scores your zones separately, estimates your body fat, and tells you which zone is holding the rest back. Rescan whenever you want to see what moved. WHAT YOU GET A routine that targets your weakest zone Your plan is built from your scan, your training frequency and where you train. It rotates as you complete workouts, so you are not repeating the same four exercises forever. Fourteen exercises, every one on video No guessing at form from a static drawing. Each exercise plays a demo you can watch mid set. A guided session, not a list Countdown, timer, rest between sets, swap an exercise you cannot do today. The camera can count your crunch reps if you want it to, and you log the rest yourself. Nutrition that follows the same numbers Calorie and macro targets calculated from your body and your goal. Log a meal by photo, by barcode, or by search. Progress you can see Scan history, workout streak, rank tiers, and a recovery day when your core needs one.
