Open the menu in the Nuki app (top left) and choose “App settings” to enter the general settings of your app. There you can configure the sound and vibration feedback of the Nuki app.
Furthermore, you can de-/activate the debug mode. When you activate the debug mode, the Nuki app stores a record of the events in your Nuki app, which helps us a lot when searching the cause of any error you have reported to us. With your help we can make the Nuki app even better!
