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. **Developer response:** Hi Gymrat34, thanks for your balanced rating in your review. While we state that HeartCast does not work with Garmin devices, we understand the desire. Please email us if you'd like to help us test HeartCast with your Fenix device. contact@heartcast.app ### 5/5 — Plays with others *2026-07-14* I appreciate being able to listen to audible, see my cycle stats on Strava and my heart rate on my phone without tech glitches. **Developer response:** Thank you, Mr Natural 57! We appreciate you! ### 4/5 — Good but ….. *2026-07-13, version 3.6.1* I use this to over come the short comings of the FIT controller on my Reise & Müller Homage 5 HS Pinion ebike. It does not see the Apple Watch as a heart rate monitor. A Bluetooth issue I believe. However, HeartCast does transfer the Apple Watch heart rate to the bike display. But in doing so it stops the Apple Activity app from running. ### 5/5 — Works well with MyWhoosh *2026-06-15, version 3.6.0* Previously gave up on using my watch for indoor cycling after how unreliable the zwift version was. Moved to MyWhoosh and realised they had no watch app, and came across this. Works perfectly, and is reliable and stable. Not a single drop out. Great that it lets me now connect to anything that needs a Bluetooth heart rate sensor ### 2/5 — When it works, it’s great *2026-06-15, version 3.6.0* ***updated review*** 6-14-2026 New version works perfectly! Thanks for the attention on fixing this app. ******************* I wish this app would work even 90% of the time. It consistently loses connection with the watch. I’m using it with ROUVY and I start the app on my phone and then initiate the heart rate tracking on my watch. It consistently drops out. During my ride, I have to quit it. Restarted it quit it restarted it. Please figure out what the Bluetooth issue is with this because that’s where the problem seems to lie. Consistently losing connection to the watch. I would love to rate this higher, but it just doesn’t work reliably enough. I’m going back to the Apple workout tracking which is too bad because it’s nice when it works with ROUVY. ### 4/5 — This is good *2026-06-10, version 3.3.2* I had difficulty understanding how to start it, still not sure. I use it to communicate with my Riese & Müller Homage 5 S Pinion. Which has a FIT controller that does not communicate directly with Apple Watch. Heart rate now on FIT display. Heartcast was a ChatGP suggestion. ### 5/5 — Simple and brilliant *2026-06-06, version 3.3.2* It just does it, no fuss. ### 5/5 — EXCELLENT ! *2026-06-03* I’ve been looking all over forever for an app that does exactly this and I’ve been searching for a long time. Finally found this one and it does exactly what I wanted. Kudos to you and it’s free! But I went beyond and purchased all the in app stuff available. Great app for the gym. **Developer response:** Thank you so much Mikey! We appreciate the kind words and your support means a lot! ### 5/5 — The only heart rate app you need *2026-05-25, version 3.3.2* Simple, clean layout and easy to use. Nothing else is needed to send your heart rate to any Bluetooth app or machine. Picks up from Watch, AirPods Pro 3, or chest strap. I use it to send data to a Concept2 rower and EXR running on an IPad. Love it. ### 5/5 — Great HR App! *2026-05-15* this app does everything I wanted it do which is tell me my heart rate. I don’t get into all the other fancy Google technical jargon. I just want my heart rate. Is that a crime I think not! bravo to HeartCast for putting out an excellent product! **Developer response:** No crimes detected! Thank you so much Johnanthony618! ## Frequently asked questions about HeartCast ### What does HeartCast do?
