Free Workout Timer

Free Workout Timer is a free workout timer app that runs entirely in your browser. Use this workout timer for HIIT, Tabata, boxing, circuit training, running, cycling, strength sessions, or any routine that alternates effort and recovery. Choose your workout time, rest time, and rounds, then begin immediately with no download, account, login, subscription, or payment.

Create a custom online interval timer or start quickly with a ready-made preset. The clear countdown, current-round display, optional chimes, and browser voice cues help you train without repeatedly checking the screen. Whether you need a simple interval timer, a HIIT timer for short cardio sessions, or a HIIT workout timer for structured gym training, the responsive layout works on phones, tablets, laptops, and desktop computers. Completed-session summaries stay in local browser storage, so basic progress remains private on your device.
