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 app is far more stable than the old CMF app. But the lack of customization on photo watch faces is unfortunate. And selecting photos for those watch faces is downright painful due to the app based photo viewer being horribly slow. There definitely need to be more options for custom watch faces and the app should allow for use of another photo app on the phone to be used.

My main use for the app, and for my CMF Watch is to control music while my phone is in my pocket. The issue I have is that the volume slider of the watch itself closes once the screen turns off, and I have to tap that tiny button to bring it back up, and THEN use the dial on the side to turn up the volume! If we could get a revision of the music area and gain the ability to more smoothly control audio with the dial while awake, I'd set the knob to do volume control at all times if I was able!
