This app does exactly what it says it does. I can now use my Apple Watch with my cycling computer to monitor and display my heart rate while riding. The developer is also very quick to respond to emails and is very helpful!

Clever app that solves a problem

Glad someone made this. I have the Garmin Edge 130 and I followed his setup video and it works seamlessly. Really glad I don’t have to wear an additional HR monitor to get this data into Garmin.

Took a little bit of fiddling but that was more to do with Apple protocols and Bluetooth priorities. But once I’d clean started the watch app and phone app I was able to pick up the signal on Karoo and see my HR on the head unit. Initial reading was zero but that was just a small lag that was quickly updated. Thanks!

Developer Story

"I wanted to ride with my Apple Watch, not a chest strap. So I built an app that just works."

As a cyclist and software developer, I built HRM to bridge the gap between Apple Watch and cycling computers. The goal: simplicity, reliability, and performance without clutter.

It’s a tool for real-world training — no unnecessary fluff, just seamless heart rate broadcasting so you can focus on your ride.
