FeelTimer

FeelTimer is a haptic countdown timer built for isometric exercise: planks, wall sits, stretches, and physical therapy holds. Feel the time instead of watching it — a gentle tick marks every second, a stronger pulse marks every 10 seconds, and a final signal tells you the hold is done, through both wrist haptics and soft beeps. Set any duration up to 300 seconds in one or ten second steps, tap start, and get into position. The countdown keeps running with your wrist down and the screen off. FeelTimer runs entirely on Apple Watch and works alongside your primary fitness app: track a plank with FeelTimer while your workout app keeps recording the full session. No iPhone needed, no account, no data collected.
