Step & sleep!

As an entry-level product, this is really good. It counts my steps & monitors my sleep brilliantly. The main reason I wanted it was for the sleep monitor information. However, it also has a useful feature that means the band vibrates either to alert you to a message, phone call or alarm. Unfortunately, this feature seems to require me to log in to the app & update every few hours, which means I frequently miss calls & messages!! I have my phone on silent on a regular basis but still need to know when I am being contacted, so if this feature worked better, it would be 5 stars.
