I use the Apple Watch as a BLE heart rate monitor for all my indoor workouts. This doesn’t work out of the box but rather needs the HRM App to transmit heart rate via BLE. This article describes how you can do that too.

I wanted to have the ultimate Apple Watch® heart rate monitor to track heart rate for my cycling training – so I built the HRM Heart Rate Monitor App that does just that.

This guide shall provide everything you need to know to use the Apple Watch® and the iPhone® App to stream heart rate to a cycling head unit such as a Garmin Edge, Wahoo ELEMNT, or others.

The Apple Watch tracks heart rate very accurately and I’d love to replace my Garmin HRM chest strap with the heart rate reading from the watch, so I built the “HRM Heart Rate Monitor” to do just that. This is the story why I did it, how it came to be, and how I'm using the HRM app for my cycling.

Every app needs terms and conditions to balance the risk for both parties – the user and the developer. Mine contain nothing special, yet you must be aware that these apply when using the HRM app.

Every app needs a privacy policy in order to disclaim how sensitive information is handled so that privacy is retained. The HRM app lays special focus on privacy, so no user can personally be identified.
