About this app

Plank Timer is a simple, focused timer app designed for your watch. Set your target plank duration in minutes and seconds, hit start, and watch the countdown on your wrist. The app vibrates as you approach the finish and records every session to a built-in history log, so you can track your progress over time. Whether you complete the full duration or finish early, each plank is recorded with the date and time achieved. Lightweight, distraction-free, and built for Wear OS.
