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.
SEE YOUR PROGRESS
Dive into session insights with interactive charts. View workout minutes by day, week, month, or year. Filter by category to see exactly where your time goes. Every session is saved with a full interval-by-interval breakdown.
