Heart Rate Monitor for Runners: Track Recovery Without a Wearable

The smartest runners track their resting heart rate and HRV daily — not just their pace. Pulse Rate gives you those metrics using only your iPhone camera.

Runners live and die by recovery: the difference between a breakthrough block and an injury is often whether you ran hard on a day your body wanted easy. Pulse Rate gives runners a morning readiness read — HRV, resting heart rate and weekly training load — from the iPhone already in your kit, no watch required.

FAQ

Your questions, answered.

How does Pulse help a runner decide hard vs easy days?

Each morning Pulse reads your HRV and resting heart rate and compares them to your baseline. A suppressed HRV is a cue to keep the run easy; a strong reading is your green light for tempo or intervals.

Can I track marathon training load without a watch?

Yes. Pulse sums your weekly TRIMP training load and charts it against your recovery, so you can manage a build without a GPS watch — just your iPhone and a daily reading.

Should I still use a watch on the run itself?

For live pace and in-run heart rate, a watch or strap is convenient. Pulse focuses on the resting and recovery measurements around your runs, which is where overtraining is caught.

Does it work for new runners too?

Yes. The morning reading and plain-language readiness score are just as useful for a first-time runner managing fatigue as for an experienced racer.
