This latest composite preview shows the refreshed zone gauge flow across Apple Watch and iPhone. It highlights the updated visual language and the kind of pacing feedback RunnersHeart now delivers during a run.

  • Unique haptic patterns for each heart rate zone
  • TRIMP-based training load analysis on iPhone
  • Workout sharing with higher quality export cards
  • Built for runners who want to train by effort, not guesswork
Why runners use it

Designed around effort-based training

From live haptics on your wrist to deeper analysis on your phone, every screen is designed to keep training simple, actionable, and personal.

Real-time zone feedback

Feel zone changes through Apple Watch haptics, so you can adjust pace without staring at the screen.

Personalized heart rate zones

Choose %MaxHR or Heart Rate Reserve (HRR) and fine-tune your target zone around your own physiology.

Zone gauge & retention cues

Follow the updated zone gauge to stay locked into the right intensity with smoother, more encouraging feedback.

Detailed workout analysis

Review route maps, heart rate history, time in zone, and training load after every run on iPhone.

Watch ↔ iPhone sync

Target zone and distance goal changes sync between devices, keeping your setup ready wherever you adjust it.

Private by design

No account, no server, and no workout upload required. Your health and workout data stay on your device.

Built for focused runs

Less distraction. Better pacing.

RunnersHeart is for runners who want their watch to coach them quietly while they run, then explain the workout clearly afterwards. The updated app experience sharpens both sides of that loop.
