GymTimer is a no-frills interval timer built for one thing: running your gym sets without fumbling with a stopwatch between reps. HOW IT WORKS Set your Work duration, Rest duration, and how many repetitions you want (2, 3, 4, or Unlimited) — then start training. GymTimer counts down each phase with a clear circular timer, plays a sound and vibration when a phase changes, and gives you a spoken "ten seconds" warning before rest ends so you're never caught off guard. FEATURES • Simple +/- steppers for Work and Rest durations • Set a rep target, or go Unlimited and just keep training • Big, glanceable countdown ring with phase and time remaining • Audio + haptic cues on every phase change, plus a 10-second rest warning • Pause, resume, or restart mid-session without losing your settings • Screen stays awake during a workout, so it won't lock mid-set • Your last-used settings are remembered for next time • Clean, distraction-free dark interface No accounts, no sign-up, no setup beyond picking your numbers. Just open it, set your intervals, and train.
