I have mixed feelings when it comes to this watch. Overall it does a decent job of keeping track of your heart rate, blood oxygen level and the steps you have walked throughout the day and the watch looks rather nice. However I feel that the user interface is rather clunky and at times it appears to lag sometimes taking 10 seconds before it does what you ask it to. Also I find that it misses a few of the exercise options that I participate in. This is somewhat remedied by the fact that you can pair the watch to work with Google Fitness which does an excellent job of tracking your exercise and it has many of the options that I participate in.
I am happy with the battery life, not so much with the app and face options, etc.
I like the watch but the app running all the time is very annoying. This is the only app I've had that doesn't allow itself to be shutoff or only run while being used. Pairing was also difficult.
Nice watch i thought I found my perfect Smartwatch. All function which I need, still looks like a normal watch without any technical stuff I wont need. Unfortunately after just 2 weeks the screen is frozen and nothing works anymore. The support was also not really uhelpful. As I left the country for a longer period and this should have been my watch for my trip there is nothing what I can do. I have a useless very exspensive watch which is not working and I dont know when I can return it. I wish the quality controll would be a bit better for a watch of this price point. I knew that the Fossil hybrids which are using the same technic having the same issue somehow I still trusted into the Citizen one.
