If you have several MyKronoz devices, you can synchronize them all on the same account.
In this case, the dashboard on the app will present an overview of your daily activity.
It is necessary to unpair a device before pairing a new one. To do this, go to the Settings section of the application> Click Paired devices > Unpair the device and add a new device.
For a better graphic representation of your activity, please only wear a device at a time and synchronize it before removing it to wear one another one.
