Sprint Intervals

Custom Interval Timer & Tracker. Stop settling for basic timers that can't keep up with your workouts.

Sprint Intervals is a precision interval timer built for athletes, coaches, and anyone who trains with purpose. Design complex interval sequences in seconds with our drag-and-drop timer builder — then let the app guide you through every rep, every set, every second.

Stop settling for rigid, one-size-fits-all timers. Sprint Intervals lets you build exactly the workout you want — then guides you through it hands-free.

CREATE YOUR PERFECT TIMER Drag, drop, and reorder interval blocks to design any routine. Assign custom categories like Work, Rest, or Cardio — each with its own color and icon. Use repeat groups to build complex sessions in seconds. Save your favorites and start them with one tap.

HANDS-FREE VOICE COACHING Never look at your phone mid-set. Voice announcements call out every transition, set number, and interval name so you stay focused. Countdown beeps warn you before each switch. Mute everything instantly when you need silence.
