Worked fine with 2 phones no problems. Started using a keypad instead on a daily basis with no problems. Tried to use the app to set up a new user for the keypad and discovered the lock and keypad aren't available in the app because I haven't used it for a while. Good job I wasn't outside with a flat keypad battery when I found out about this "Feature"

Horrible app, horrible product. Today the app decided to wipe all my settings "for security reasons" - banking and creditcard apps are fine, only Nuki. I have used multiple of these locks, stopped using them because the locks failed without any warning. Support cannot be reached, no phone number on the site and the chat does not respond.

The app is very easy to use and functional, and so is the lock itself. A few improvements would be: better, more customizable smart notifications and if the widget would automatically update after each triggered action. It's kinda useless to have a widget to see the status but then have to manually refresh it to actually see that status. it should trigger a refresh whenever codes, keys or fingerprints are used. I bigger widget would be good as well.
