IntervalRunner: Pace Coach

Pace alerts: voice & haptics

Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.

Drift off pace and you'll know instantly — by voice, tone and a tap on your wrist. Run every interval as planned, with or without Apple Watch. Run every interval exactly as planned. IntervalRunner checks your pace against your target and tells you the moment you drift — by voice, by tone and with a tap on your wrist — so you never have to look at the screen. ALERTS YOU CAN TRUST • Smoothed pace instead of jumpy GPS, with a tolerance band you choose • Different tones and haptics for too fast and too slow • Natural AI-generated voice cues that lower your music and keep working with the screen locked BUILD ANY INTERVAL • Time or distance steps with a target pace or speed • 14 editable presets: 400 m repeats, Yasso 800, ladder, pyramid, fartlek, tempo, run/walk and more • Slow jogging and Zone 2 presets keep easy runs truly easy, with a cue the moment you speed up (Zone 2 heart-rate target with Pro) • Three count modes: start when you reach target pace, count only while on target, or count right away • Auto-pause per workout, km or miles, pace or speed WITH OR WITHOUT APPLE WATCH With Apple Watch, the watch measures and taps your wrist while iPhone shows the numbers and speaks. No watch? Run with iPhone alone — or with just the watch. Treadmill mode needs no GPS: run on time at the speed you set on the machine, then confirm the distance from its display. After each run, see target vs. actual for every step. Workouts are saved to Apple Health. FREE Everything you need to run: the builder, presets, all alerts and count modes, treadmill mode, unlimited history, Apple Health, Live Activity, GPX/JSON export and 3 saved workouts of your own. Step analysis is open for your first two runs. INTERVALRUNNER PRO • Step analysis, trends and personal bests • Heart-rate zone targets, and recovery that ends when your heart rate drops • Unlimited saved workouts and folders • Nested repeats and ladder, pyramid and Yasso 800 generators • Per-second CSV export Heart-rate features need Apple Watch or a Bluetooth heart-rate monitor.
