About Plank Form Timer: AI Check

Plank Form Timer counts only the seconds you actually hold good form. Stand your phone at your side and start. The clock runs while your body stays in a straight line and stops the moment your hips sag or pike, so your record is honest. A TIMER GATED BY YOUR FORM • The clock pauses when your form breaks and picks up again when you recover • Instant cues: lift your hips, lower your hips, straighten your body • Voice call-outs every 30 seconds so you never have to look at the screen KEEP THE SESSION AS A VIDEO • Save a video with the skeleton, hold time and pause reasons drawn in • Sound is captured too, so you can hear the cues again later • Date, time and your approximate area are stamped on the video • Recording can be turned off any time in Settings ONE VIDEO FOR THE WHOLE DAY • Join a day's sessions into a single clip at 1x, 2x or 4x • Skip the paused parts so only the time you truly held remains • Save to Photos or share it SEE YOUR PROGRESS • Daily total, longest hold, breaks and calories • A calendar with a grade for each day • Swipe left and right to look back at any day Everything runs on your device. Videos and audio stay on this phone unless you share them yourself, and no account is needed.
