Heart Buddy - Peace of mind and simple to use

Heart Buddy is an easy to use iOS app for the iPhone or iPad. Heart Buddy continuously monitors the heart rate and raises an alarm when it detects a low or high heart rate. This could be indicative of a seizure, a problem with a pacemaker, or other heart problems.

Heart Buddy is totally free: no subscriptions, no adverts, complete access to all advanced features. Heart Buddy is already helping people and it can help you too.

  • Continuous, realtime monitoring of the heart rate throughout the whole night, the day and wherever you go.
  • Customise Heart Buddy's alarms: including those for high/low heart rates; low battery; signal loss; and more.
  • Heart rates displayed on charts and updated as each heart rate is collected.
  • Heart rate saved on the device and optionally in the cloud.
  • Review heart rate charts from those saved in your history to spot patterns and gain valuable insight to heart rate behaviour.
  • Share heart charts to your other devices, family, or email them to healthcare professionals.
  • The Heart Zones feature keeps you informed of heart rate changes without even needing to look at the app.
  • Optionally connect your iPhone/iPad to a bluetooth speaker to allow alarms to be heard remotely, elsewhere in the home.
  • Heart Buddy can now share your heart rate with the iPhone Health app.
  • Designed and tested with the Wahoo TickR Fit Heart Rate Sensor with up to 30 hours battery life. Also works with other bluetooth low-energy (BTLE) heart sensors.
