I'm giving this as a Christmas gift. Once I received the smart watch I had to charge it, once that was done all you need to do is link it up to your Samsung phone and your good to go. Very simple to hook up and simple easy to use, since everyone should know to use their icons. It's amazing on all the features this watch can do. My son tested it out forme since his always exercising an dbeing fit. He states it's a great product to buy.
