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
