Heartrek

Your heart is the controller.

Cardio doesn't have to be boring. Heartrek is a workout app that turns your live heart rate from your Wear OS watch into speed on a 3D course shared with others. Push harder and you speed up, ease off and you slow down.

  • Works with any cardio: treadmill, bike, rower, or elliptical
  • Guided zone training, from steady fat burn to hard intervals
  • Race pacers and see other people working out live

Live Heart Rate Pro

Advanced heart rate and cardio tracker for Wear OS.

Live Heart Rate Pro records and analyzes your heart rate over time, using your Wear OS watch or a Bluetooth heart rate monitor, and tells you what you need to do to hit your goals.

  • Time and calorie goals, with the pace you need to finish on time
  • Compete against a past workout, or beat it by 10%
  • Heart rate zones, high/low alerts, and vibration alerts on your watch
