Yes, you can store multiple heartbeats in your heartbeat library!
However, you can only wear a single heartbeat at any given time. If you want to switch the heartbeat stored on your Bond Heart, you can do so in the heartbeat library on the Bond Touch app.
Changing the heartbeat you’re wearing requires waking up your Bond Heart, so it can pair with your phone via Bluetooth and proceed with the update.
Select the heartbeat you want to wear, and you’ll then be instructed to firmly press both sides of the Heart while tapping it on the side until a short vibration is felt.
