Active Pro smart watches connect to iOS and Android phones via bluetooth connectivity.  The watch operates via its very own App. Technology; The V-Band App.  You will need to download the App onto your mobile phone device to begin syncing your mobile phone data to your Active Pro Smart Watch.
Each individual model in the Active Pro range has its very own set of instructions that make connecting your device easy.  It is recommended that you follow the instructions as they appear in the manual of your Active Pro model.
Depending on the features included with your model, your Active Pro watch will sync via bluetooth to your phone's device and allow you to begin interacting as you would normally on your mobile phone, assuming it is within the mobile phones range.  The App will allow you to control your watch and monitor your data.
