Great App for Apple Watch

I was looking for something that I could use other than the workout app already installed on my Apple Watch and this is it. It works with my Wahoo Heart Rate monitor that I bought 2/3 years ago. I think its more accurate than the heart rate on my phone. Im only giving it 4 starts because if I start it on my phone it wont stay open on my watch. Great app.

Ownbey about Wahoo RunFit
