Distance Interval Trainer

Intervals by distance, not time.

Distance Interval Trainer is built for runners who train by distance: 6 × 400 m on the track, mile repeats, or 1 km efforts. Set your intervals, start on your iPhone or Apple Watch, and get a voice cue or a tap on the wrist at every mark. The big number shows exactly how far is left in the rep, so you never have to do maths mid-run.

FREE • Intervals by distance or time, in km or miles • Warm-up and cool-down in the same workout, including Open: warm up as long as you like, then tap Start Intervals • Voice cues for Run, Rest, Finished, "Round 3 of 6" and "Last one" • Hold to Stop, so a sweaty wrist can't end your workout • Outdoor runs on iPhone, plus 3 runs on Apple Watch • Saves to Apple Health

PREMIUM: one-time purchase • The full Apple Watch app • Adjustable wrist taps • Indoor runs (treadmill and indoor track) • Your workout history

COACH: one-time purchase, includes Premium • Full voice coaching: halfway, split times, target pace with ahead/behind cues, and heart rate • Heart-rate limit alerts on Apple Watch • Track mode: tap at the line each lap for accurate splits when GPS drifts, with 400 m, 200 m or custom tracks and automatic lap counting • Saved workouts, ladders and pyramids • Repeat until a total distance, like 400s until 5 km

No subscription and no ads. If you bought the app before it went free, Premium is already yours.

Works with the Action button on Apple Watch Ultra and makes full use of both screens on iPhone Duo. Available in English, French, Spanish and German.
