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.
