Heartener®: hear your heartbea

- Hear the effects of meditation as you focus only on the sound of your heart.
- Eliminate racing thoughts as you fall asleep by focusing only on the sound of your heart.
- Hear the effect of your workout on your heart rate as you exercise.

Heartener® uses the heart rate sensors on your Wear OS device to translate your heart rate into a sound that is played on the Android phone paired with the watch. If your heart rate moves outside a range you select on the app, a very loud siren alert will automatically sound. You can also manually trigger this alert sound from your watch or on the companion app running on your phone.

Using the heart rate information is transmitted to your phone, every 5 seconds, the heartbeat sound effect is played based on the latest heart rate received. The pitch of the heart beat sound is lower for slower heart rates, and gets higher as the heart rate increases. The color of the heart rate text display varies from green to bright orange depending on the heart rate beats per minute.

To begin the Heartener session, first open Heartener on your phone. Open Heartener on your Wear OS device, and tap Activate. You'll get voice confirmation the session has begun, and within a few seconds the first heart rate data will be transmitted. To end the session, tap De-Activate on your watch, and your phone will give you voice confirmation the session has ended.

Heartener requires your authorization for vital signs sensor data access on your Wear OS device. Heartener will not function if the paired phone is locked or in sleep mode. No health information ever leaves your devices, no account creation is needed and the app contains no analytics tracking your usage.
