Took me 6 hours using a weekend to get this to connect to my smart phone. It is beautifully designed but it does not work. I downloaded the software to my Samsung and is what I'm experiencing:
Chinese won't translate to English for Set-up
Length and Weight take my data but then converts the In to Cm
Lbs to KG It would work and then change to the metric system but not convert the data where 2.54 CM =1 inch, if you put 65 inches it reads 65 cm after you return.
There are two programs that I downloaded both are identical but different names, Smartwatch and BTNotification
Wrist watch is great looking. It kept deleting the little data I created because it is very difficult to maneuver the very small key device. It would drain it's battery in less than 2 days I dad it and I recharged it three times. It searched for my device and my device searched for it and never the twain shall meet. In fact it connected with the BT Band Audio but never the device. Too many issues. I don't think it's my device, I think t is the overall programming and design of this watch.
I can't even use it as a watch, it fluctuates between military time and HH:MM.
It needs a user manual with complete instructions on using everything. There was quite a bit of information in the watch you can use as you moved from one app to another but no way to know what to do.
