About this app

RoundTimerX is an interval timer built for structured timed activities - team sports, training sessions, and personal workouts.

Whether you're timing basketball quarters, soccer halves, HIIT circuits, or any other round-based activity, RoundTimerX lets you build exactly the sequence you need and stay focused on the action.
