Awesome watch!! I had a problem with your menus but finally figured it out. It has everything I need plus a whole bunch of other great stuff - like setting commonly used numbers and their pictures!! I love that. Compared to other watches this one is less than half the price with twice the usability. I would normally say "Nothing is perfect" but this time it really is perfect. Yes! Nothing Is Perfect!! As for battery life - 10 hours ago it read 86%. It still says 86%. Thank you, Nothing!!

The health tracking app for my CMF Pro 3 watch worked great. For a while. Now, it constantly says "network is poor" or "server is busy", despite being connected to my WiFi. The health functions on my watch still work great. It just isn't communicating with the app. The portion of the app for my headphones still works great. I'm not sure why it is refusing to communicate with the watch.

App ruins the watch experience. It works well enough for syncing headphones and messing with settings, but that's it. If you were interested in the CMF watch, the app makes the features of the watch nearly irrelevant. There's very limited insight into what any of your data means, and more often than not it doesn't even sync. I continuously see an error message of busy servers or slow networks which disallows the app to display any of the relevant data, none of which can be viewed on the watch.
