Plank

Thirty seconds today, a little more tomorrow. Plank takes you from a 0:30 hold to five minutes in thirty days — then keeps going with harder plank shapes instead of ever-longer holds. Every target comes with its reason. Hold it clean and tomorrow moves up. Mark a hold as hard and it repeats. Stop early and the app records what you held and starts from there — stopping honestly is part of the plan, not a failure. - Today: your target in a ring, the line explaining it, and one button to start - The hold: near-black and eyes-off, with a voice coach, haptics, and tap twice to stop - After day 30: five shapes, from long-lever to side plank, each starting lower and climbing again - Record: the 30 days, every day since, and the shape ladder - Streaks that count prescribed rest days, with one earned mend a week for a missed day - Widgets and Live Activity: today's target, your streak, and the hold on your Lock Screen and Dynamic Island - A daily reminder that names your target No account, no tracking, no data collected. Everything stays on your iPhone.
