In order for the app to function with our trackers you must enable Bluetooth and Location permissions for the app. It is preferable to enable these when first setting up the app after installation. When the app is launched for the first time you should be notified by your phone that KatchU requires permissions. BluetoothBluetooth permissions are required because the tracker uses a Bluetooth connection with the tracker to communicate any updates or settings changes made in the app. BLE is also required if you wish to utilise Bluetooth Beacons around your home to increase indoor tracking accuracy. Please enable BLE permission if requested.
