I bought this watch as a Christmas present for my son, it was fantastic, the app was good, allowing you as a parent to set tasks so they earn coins which they can redeem for a treat, although the app crashed quite a lot but overall it was useable.

There are bigger more expensive fitness bands out there. This does everything you need it to. Step count ,stopwatch, time etc and no need to charge it which is fantastic.

I just purchased this product packaged with a heartrate monitor. You're supposed to cycle through functions by pressing the device key and you're supposed to get a heart icon for the heart rate functionality. This device doesn't have that option.
