PlankCoach is not just another app blocker. It blocks the apps that pull you in — and makes you earn your screen time back with real planks. When you reach for a blocked app, PlankCoach locks it behind a shield. To unlock time, you hold a plank while AI judges your form in real time through your camera. If your hips go too high, too low, or your body line breaks, PlankCoach warns you immediately. Bad form does not earn time. Only real planks count. Real form. Real effort. A stronger core — and screen time you actually earned. How it works: 1. Choose the apps you want to block. 2. When you open one, it stays locked until you have balance. 3. Place your phone horizontally near the floor so your full body fits in the frame, and hold a plank. 4. PlankCoach checks your form with visual and voice feedback and turns honest plank time into app-time balance. 5. Spend that balance on your blocked apps — up to your daily limit. Unused balance never expires (Pro). Why PlankCoach is different: - Most blockers rely on willpower or a tap-to-ignore button. PlankCoach makes the price of screen time real, physical effort. - AI form detection keeps you honest — no fake planks, no padded numbers. - You break the doomscrolling habit while building a stronger, more defined core. - Hard Mode adds a commitment lock, so you can't bail the moment it gets hard. What you can do with PlankCoach: - Block distracting apps with Screen Time and unlock them by planking - Real-time AI plank form checks using your camera - Visual and voice alerts the moment your form slips - Earn app-time balance for honest planks and spend it on blocked apps - Your balance never expires — unused minutes keep stacking up (Pro) - Set your own daily usage limit (30–180 min) - Hard Mode: a commitment lock that prevents turning blocking off instantly - Block streak: see how many days in a row you've stayed on track - Front, side, and reverse planks (side and reverse are Pro) - Set menus that combine plank and rest intervals (Pro) - Progress tracking: an achievement calendar, total and longest plank, and core-level progression - Weekly app-usage insights - Share your results - Move your data to a new device with a transfer code (Pro) Free and Pro: - Free lets you block up to 3 apps and earn your screen time with front planks, including Hard Mode and progress history. - PlankCoach Pro unlocks blocking up to 50 apps plus entire categories, side and reverse planks, set menus, a balance that never expires, and device transfer.
