IntervalSmith is a precision interval timer built around the way you actually train. Stack warm-up, exercise, rest, and cool-down stages into unlimited sections, set repeats per section, and let the app run the clock while you run the workout. BUILD YOUR WORKOUT Create any interval structure in seconds. Add multiple sections, each with its own stages and repeat count. Need rest between rounds? Set it once — IntervalSmith handles the math automatically. AUDIO & HAPTIC CUES Never miss a transition. Distinct tones mark each stage type, a 3-2-1 countdown ticks before every change, and an optional halfway alert helps you pace yourself. Everything works through your headphones. APPLE WATCH (Pro) Run your workout from your wrist. The Watch app mirrors your full interval structure with a smooth progress ring and live countdown — staying accurate even when your wrist is down.
