Beast Plank - AI Plank Timer

MOVE, AND THE CLOCK STOPS.

Beast Plank is a plank timer that watches your joints in real time through your iPhone's camera. The clock only runs while you hold still. Drop an elbow, sway a hip, and it stops instantly. The beast does not miss.

WHO IT IS FOR

• Anyone whose "one minute plank" is really 40 seconds of shaking
• Anyone who keeps counting while their form falls apart
• Anyone who wants a referee at home that cannot be fooled
• Anyone building a daily core-training habit

AI STILLNESS JUDGING On-device pose estimation tracks your upper-body joints - head, shoulders, elbows and wrists - and up to 17 in total with lower-body judging on. Beast Plank measures how far each joint drifts and turns the moving ones red. Detect motion and the timer pauses automatically; hold still and it resumes on its own.

SEE WHAT MOVED The screen names the joints that broke the hold, like "(L Shoulder, R Elbow)", so you learn exactly where your form gives out.

TUNE HOW STRICT IT IS

• Strictness: level 1-10. Higher levels react to smaller movements.
• Reaction window: 0.2-2.0 seconds. Shorter reacts faster, longer tolerates wobble.
• Countdown: 3-30 seconds to get into position before the clock starts.
• Lower body: off by default, because the far leg hides behind the near one in a side view and causes false positives.

FRAMING GUIDE Live guidance tells you when you are too close or too far, so your whole body stays in frame. If a joint leaves the frame, the timer stops as well.

YOUR RECORD, KEPT Every cleared session is saved on your device: total sessions, total time, personal best, and the duration and pause count of each hold. Finish without a single pause and you earn the NO-STOP badge.

45 LANGUAGES The app follows your device language on first launch, and you can switch any time in Settings.

PRIVACY: THE VIDEO NEVER LEAVES YOUR IPHONE
