Interval Pulse Timer

Build your own HIIT workouts and run them with a clean, focused interval timer. Interval Pulse Timer lets you create custom sequences of named, color-coded intervals — work, rest, warm-up, whatever you need — repeat them for as many rounds as you want, and run them with a big countdown ring, sound cues, and haptic feedback so you always know what's next without looking at your phone. FEATURES • Build unlimited custom workouts with named, colored, timed intervals • Apple Watch app — start any workout from your wrist with full run controls, and finished workouts sync back to History on your iPhone • Live Activity — see the current interval, round, and countdown on the Lock Screen and in the Dynamic Island while a workout runs • Optional warm-up and cool-down segments (with their own colors) that run once, not per round • Repeat any workout for 1–99 rounds, or instantly re-run it from the finish screen • Drag to reorder workouts and intervals • Big countdown ring with round progress and "next up" preview • Audio + haptic cues for interval changes and the final countdown • Screen stays awake during a workout • History tab with streaks, weekly totals, and a habit-tracking calendar • Light, Dark, and System appearance • 100% offline — no account, no ads, no tracking. All data stays on your device. Whether it's Tabata, EMOM, or your own custom split, Interval Pulse Timer keeps the workout simple and the setup out of your way.
