You will need to pair/connect the Band with any Android or iOS device running at least Android 4.3 or iOS 7.1 (iPhone 4 excluded) respectively. This phone/tablet must also possess Bluetooth low energy capabilities. You'll need to download the Striiv Activity Tracker app to the phone/tablet and create an account to pair the Band with the app.

I purchased the Striiv band (wireless band activity and sleep tracker) because I was told it was compatible with my Kindle Fire HD. I can not sync the two of them and make the band work. HELP!!!!
