Running Companion

Heart rate zones and intervals

Free · Designed for iPhone. Not verified for macOS.

Zone 2 made simple: connect a heart rate strap or Apple Watch and hear when to slow down or speed up, even with your iPhone locked in your pocket. Running Companion coaches your runs, intervals, Zone 2 sessions and hybrid races, with live heart rate alerts and spoken cues that keep working while your iPhone is locked in your pocket. TRAIN IN THE RIGHT ZONE Set your max heart rate once, then give any part of a workout a heart rate zone or start from the ready made Zone 2 Run. Connect a Bluetooth chest strap, an arm band, a tracker that shares its heart rate, or your Apple Watch. Drift out of your zone for ten seconds and you hear "Slow down" or "Speed up" with a haptic on your iPhone, repeated every minute until you are back. INTERVALS THAT FIT YOUR WORKOUT Build workouts from timed, distance and open segments, each with its own timer. Recoveries can end on time, or when your heart rate falls to the number you choose. Every segment change is announced, so you never need to look at the screen. HYBRID RACES Practice race day with eight 1 km runs between eight strength stations, each timed on its own. Indoors, distance comes from your steps. GPS RUNS Distance and pace live from GPS, an audio cue at every kilometer or mile, and elevation gain saved with every outdoor run. Turn on Auto Pause and an open run stops the clock when you stop and starts it again when you move. LEARN FROM EVERY RUN History keeps each workout with its splits, its segments and a heart rate chart that shows how long you stayed in, above and below your zone. Outdoor Zone 2 runs of 20 minutes or more show their aerobic drift, and Running Companion suggests a higher max heart rate when your recent runs show one. APPLE HEALTH AND APPLE WATCH Finished workouts are saved to Apple Health with their distance, route and elevation, next to the heart rate and calories your watch already records. With Apple Watch as your heart rate source, Running Companion opens on your watch when a workout starts and streams your heart rate to your iPhone every second. PRIVATE BY DESIGN No account, no subscription, no ads and no tracking. Your workouts stay on your iPhone and in Apple Health.

Ratings & Reviews

  • This app hasn’t received enough ratings or reviews to display an overview.

A redesigned Running Companion, built to be read at a glance mid run. • The live workout screen shows one big number, a bar of the whole workout with what comes next, a heart rate zone gauge and controls sized for a moving thumb. Finish now sits behind a press and hold, so it can't be hit by accident. • Edit a workout right where you see it: tap a segment to change it, swipe to duplicate or delete it, hold to drag it into place. • Repeat blocks: build "Hard 2:00 + Recover 1:00, 4 times" as one block instead of eight segments. • Indoor workouts let you correct the distance from your treadmill or tracker before it goes to Apple Health. • History is grouped by week, with clearer heart rate charts, splits and segment results. • Fixed a Motion & Fitness prompt that could appear after an outdoor run.
