Sport Timer

Sport Timer makes it easy to plan and run structured interval workouts—especially for coaches, sports groups and athletes . Create multiple workout profiles, set prep / work / rest times (in seconds) and repetitions, then start the timer and let it guide the session with audible signals. It can also keep running while you use other apps (for example, to control music).

Privacy-first by design

No account needed: you can use the app immediately—no login, no signup.
No data collection: the app is built to work locally and doesn’t collect, track, or sell personal data.
No ads: ad-free experience with no third‑party advertising SDKs.
Free: the app is 100% free to use.

Perfect for HIIT, circuit training, team warmups, or any routine where you want clear timing, repeats, and a clean, distraction-free interface.
