Perfectly simple

Sometimes people don’t complicate things and it just comes out better. That’s what this app does. Super simple, clear, extremely easy to pair after you load the app onto your watch it just works! Nice features and options

Wahoo Element Bolt Integration

My Wahoo Ticker device died due to overuse. The thought of having to spend $80 for a replacement really chapped my hide. Thought I may have to bite the bullet and spend the money. Then along came HeartCast. It was easy to pair with the Element Bolt. I did need to update the firmware on my Element Bolt. So far I have the phone, watch combination paired with the Element Bolt. Still need to perform a ride with the setup. Will update.

Heartcast

Great heart monitor program.

Not for Garmin

Disappointed! Tried connect to Garmin Fenix 8 Pro sapphire using AirPods Pro 3 with no luck. Fenix sees Heartrate cast but will not connect. Hoping this will work in the future. 4 stars because of the pricing model and the ability to test before buying. If it would connect I would buy without reservation. Does display HR from AirPods Pro 3 on iPhone without issue.
