Will not pair or detect Apple Watch so the app is non functional on Apple Watch, despite loading perfectly. It recognizes the Watch but the sensor is non functional. Very intriguing app otherwise. Great design.

Will not detect Apple Watch 4 or sync with iPhone 10xs Max. Sensor not found. Just spins. Hooked up to my iFit Bluetooth sensor once. The app would be great if those things worked. I contacted through twitter. Answered my first question then nothing after

I have searched the App Store for a long time for a heart rate app that will give a voice prompt or alarm so you don’t have to look at your watch or phone every few minutes. This one does both. I haven’t put it thru all the paces as far as all the other features, but for what I need it fits the bill.

Tells me when I drop out of a heart rate zone - the only app I’ve found to actually do this. However I would love if it also told me when I enter BACK into the heart rate zone too!
