After initial disappointment afterwards but good

The clock I have now worn daily since the beginning of January 2015 and walked also usually 2x a week => Everything without problems, and the battery lasts me a good 2-3 weeks without charging dutch.

The software on the Mac and the firmware of the clock has been updated in the meantime and now you can sync the data to the computer without problem.

Unfortunately, the iPhone sync problem is nothing improved, but I deal now by the fact that I now once a week transfer my data on computers => This is really the only thing that's missing!
Here I hope to further updates to the app and the upcoming iOS 8.3

I was really looking forward to this clock, was already through the Nike Fuelband (1 + 2) some accustomed to pain, but that simply is not fun to date. The clock itself works quite well, but they can only luck (MacBook Air, MacBook Pro, iMac, iPhone 6 and iPhone 6+ tested), but mostly not synchronize. First came several hours an indication that the flow service is unavailable, then had to be installed a firmware update, which did not want to take out / could and then the flow-sync tool is repeatedly crashed (usually immediately; whether connected clock or not). Having been at some point synced my data (weight, size, Metric ...), I thought I'm out of the woods. However, it was then the settings partly not accepted (weight in pounds is suddenly and size in ft => Took me then no longer even bothered ...). Anyway, I thought then, now time to make a difference and sync the data in the app. That has now worked in the 5 days that I have this clock exactly 1x. The procedure is always the case that the clock is coupled to the iPhone via Bluetooth, but then nothing happens. The clock is then 5-10 minutes unusable and appears at the end of an error message. Very bad! I hope that improved Polar again right after. I can also recommend a look at the reviews for the app to take, because this problem seems a lot of people have currently :(
