This watch seems to be a good little watch but it will not sync Sleep Data, knows Military Time Only and needs more updates! If it wasnt for that it would be a watch I would keep.
I have a iPhone 6s Plus and finally synced with the watch after several tries and it took me time understand each screen for sport, sleep and heart rate.
See below:
To sync each time you pull down on the screen, to go to your details for each you hold or touch each circle that switches to another screen for you daily, weekly and monthly results. Then you sweep to your right that will take each individual scree showing the time, graphs and total for each day.
This could really be a nice little watch if it wasnt for the above problems. The band is ok but they could somehow make it better in its own right.
I hope the developers are reading this because we rely on you to continue the changes and updates.
If you want me to keep mine please try an update for syncing sleep, options on US time or overseas. If not I will be sending mine back. Until then I will wait or follow up with another review soon.
