Enable Bluetooth in the settings of your smartphone and start the FITvigo app. Make sure that Bluetooth is turned on and that the FITvigo app is open to perform the pairing of devices.
Tap VIGO in the FITvigo app and then on "I want to pair my FITvigo product!".
Another option is in the app's settings. Tap "Pair new FITvigo product" in the "FITvigo Products" field.
Now press the button on the side of the Smart Activity Tracker until it vibrates twice. The connection icon now appears on the display of the Smart Activity Tracker.
Once the FITvigo app finds the Smart Activity Tracker, you can confirm the connection on your smartphone.
Please note that Bluetooth must be enabled on your smartphone so that the measured data are synchronised with the FITvigo app.
