Very solid app

Firstly, i have the Polar m400 which is an awesome watch. I'm impressed with this app too. I prefer this to the desktop, which isn't as flawless when syncing (download a new version and lose my data? Nope) and so far this works fine mechanically. Feed Interface is a little cluttered and seems harder than it should be to navigate back through the calendar and see timings. Pretty good graphs, trying to see if there's a way to compare timings but that is my only nitpick. Might have to import into Excel. As mentioned, the watch itself, an m400, is Rock solid after busting a few Garmins that are irreparable. Very simple easy to use menu. It just works.

Slow Heart Rate display and inaccurate sleep tracking.

I like most things about the App and my Polar Vantage M. However there are two areas needing significant improvement. These are:
- The delay in displaying heart rate. Because of this delay it is easy to overshoot my maximum heart rate while exercising. I have verified this delay by comparing the M’s reading to that of various pieces of exercise equipment. However, when hiking, or doing other activities, without another piece of equipment to track the actual heart rate it is easy to overrun, or underachieve.
- Like many people over the age of 60, I have to get up during the night to relieve myself. Unfortunately the Polar Vantage M and or the Polar app think that I rwmain awake from that point forward, even though I do go back to sleep. Again, I see a very substantial difference between what Polar believes is my sleep time and that shown by my CPAP machine...
PS: Every NickName I tried to use to submit this review was reported as taken, including “AllNickNamesTaken”, so I am about to resort to a random collection of characters to see if that will work.........!!!!!!!!

Syncing is a mission

Im a fairly new user - only got my device a month. Although I like the look and feel, syncing is not a simple task. I’ll sink and expect it to be working only to find that it hasn’t or hasn’t uploaded a full days results. I’ve resorted to taking the device off and placing it on my cellular screen to sync as alternatively suggested and although that appears to work better, at times it throws the time off. Last Friday was such an example and got me into some trouble for thinking I had to leave a meeting already only to find out I had the wrong time. Embarrassing and frustrating! I had a much cheaper device and experienced none of these challenges in the past. If this experience continues, I’ll have no choice but to revert back to the old device. Pity is I bought an extra four devices to give as Christmas gifts and at the moment, I’m regretting have done so as I expect they’re going to be frustrated too.
