What a great app and what a great device the M430 is. Love being able to just glance at my pace and heart rate while out running. And best accuracy in the field too. The Flow app is very well designed and offers an amazing list of sport profiles. The device and app have also made me more conscious of sitting too long at work. As a self employed person I was too prone to sit for hours. Now I make sure I get up and walk about a bit when the device buzzes. My only gripe is that the device isn't particularly easy to wear when sleeping. I never used to sleep with a watch so I find myself waking up because of it snagging on a pillow or something. It's a shame because I like the sleep tracking feature. Maybe it just takes getting used to. Thanks for reading my review.

Syncing issues

Please can something be done to help this. My polar flow 2 will go for a couple of days without syncing and then requires a lot of time and effort to get it started. Currently it hasn’t synced for 2 days & despite what I am doing now, I can’t get it to start the process. I’ve had a couple of error messages saying the process cannot be completed. I’ve tried taking it off, touching the connector, restarting the app and the phone and that has NEVER worked. Any other solutions? I see the app was recently updated. My biggest issues have come since then.... Sad because when it’s working correctly I think it’s great

Overall a good watch but...

I do like my Polar A360 except for one issue. I travel. A lot. And my watch does not seem to enjoy it as much as I do. Once my phone resets time upon landing in a different time zone, it is like my watch no longer exists.

I try and I try to sync; or to even to connect with my phone. No luck. Sometimes I can’t even get it to pair with the website via my laptop.

But the moment I land at home, it is like they were never parted.

It would be nice if they came up with a nicer band for wearing it outside of the gym. Something you could pop the watch bit into. Since the watch bit often tries to escape my current band; so far I have managed to catch it before it makes its escape. Something in a nice leather maybe with a bit of sparkle to it.

For the exercise part its fine for where I am and what I do. Swim and gym etc. I really like that you can swim with it. Adding “Dog walk” to the exercise menu would be nice.
