I use Fitbit almost one year. I need a USB device to synchronize data it collect. The USB device should work with PC and its program, Fitbit connect.
Now Fitbit syncing support more devices.
Including iPhone 5s, iPhone 5c, iPhone 4s, iPod Touch 5, iPad Mini, etc.
Most important news for me is that it is supporting Nexus 7 (2013) now.
It means I don’t have to turn on my PC and sit beside it to wait the data synchronizing. I can play my favorite games,Jewel Mania, Fragger, Candy Crush, or Angry Birds, the data syncing is done without further action.
It is just because of new Bluetooth. Supported new Android devices are all have following two features.
- A Bluetooth Low Energy (BLE) radio, present in some devices as part of Bluetooth 4.0.
- A working BLE API that allows third-party app code to access BLE. This is present in some Android 4.3+ devices.
So if you want a new device, make sure it has above features.
