Watch works App does not

The watch records my steps and the time. In order to view it on the phone you need to sync it but the app is constantly losing the previous day so you can not compare daily activities. As for sleep, I have given up. The only way I have found it to track sleep is to bind and in-bind it over and over. Bought two watches one IWon and this one for the same price. I love the IWon watch (does not track sleep but does everything else better) and this one was given to my kid for instant gratification without daily comparisons. I would not suggest this watch due to the app.
