A no-frills interval timer built for the gym floor. Pick a preset or build your own, hit start, and train. Big readable display, audio and voice cues, and it keeps your screen awake so it never blacks out mid-set. Free, no signup, works right on your phone.
A timer keeps you honest on the clock. A real program and a coach keep you progressing. Explore our training programs or work with a coach at Grinder Gym.
