Hi guys! I’ve made a small Apple Watch + iPhone app with which you can use the Apple Watch HR with TrainerRoad. It exposes the heart rate of the Apple Watch by sending the data to the iPhone,
which then sends it to any other device by mimicking a bluetooth heart rate sensor (I tested it with TrainerRoad and the Hammerhead Karoo bike computer, both work 
). It’s still very beta (first test was yesterday, but if anyone is interested in helping me test, just email me at heartbyproxy@jorritposthuma.nl ).
