Broader integration required

This is my preferred training App today but it would be so much better if it could pull in data from devices other than just Polar. While I use my Polar watch for some sports, I use other devices and sources for other sports. This means I need multiple Apps and don’t have a single integrated view of my training unless I resort to things like Strava - which I really do not like. I’d also like to see more direct data and analytics around training and recovery. The high level workout level categories are sort of cute, but real numbers are easier to use for serious training.

Awesome

Still loving and even better with Polar Grit 2

Force you to give up privacy

I paid for the sensor. The app is “free” except that the only way it works is if you agree to let Polar collect, sell and do whatever they want with your data. This should be criminal. I returned the H10 and bought a Garmin because of this.

Not overly joyed

It’s quite cheaply made and won’t automatically link to Strava. The screen isn’t very sensitive so trying to swipe isn’t reactive enough.
Stopping the watch after an activity and having to hold for the counter to tick down isn’t great either.
Although the watch is pretty and looks great.
It is accurate in distance tracking and GPS.

Great app with some fundamental cross platform limitations

Really like the device and the app and the working. Good job.

My issue really is its ability to sync full data with Apple health. For example it only shows the sleep length, not the different stage (light, REM etc). Unfortunately it falls at the last hurdle.
