Polar (For Real Training Feedback)
The way this app works with the phone and/or Apple Watch its better than the Polar V800 for indoor training. Time in zone on watch & web. Recovery chart, Training load plus lots of analytical data on Polar Training website. Works good outside as well if you take your phone. Apple Watch HR is not accurate at all for exercise. Pair with H7, Rhythm+ or other Bluetooth monitor for real accuracy. Dont blame the app for hardware issues. Currently using this with a Rhythm+ paired to Apple Watch as a health device. Works great and as accurate as my Ambit 3.
