Planck time is the shortest measurement of time possible. Plank time, however, is a lot longer than that. This is a simple, standalone WatchOS app that integrates with Apple HealthKit and focuses on one thing: Planks! This plank timer uses haptic feedback to alert you every 15 or 30 seconds (customizable to your preference), with stronger buzzes at each minute - one buzz per elapsed minute. Use this as part of your daily workout routine to precisely log your plank durations, and know that your fitness data is being stored safely and securely on-device; we do not collect or sell any of your personal data.
