iOS 13 Crashing Still

Expected some apps to fail during initial betas of the new iOS 13 several months ago, but with only days left before the official launch of the new multi-device OS update - this app still crashes before even loading. I have a feeling there will be a lot of people locked out of their places come Friday morning with zero warning.

Update: Looks like the team was able to slip in a fix under wire post the iOS 13 launch! Still some stability issues and the turn to unlock feature doesn’t always behave - but systems are back up. Good job Dev team!

Developer Response ,

Hi there! We do apologize for the trouble you experienced while on the iOS 13 beta, but were able to release a new update that includes support for the new Operating System. We do recommend updating to app version 1.9.1 whenever is most convenient in order to restore full app functionality. Quick, reliable property access is our top priority for all users so if you continue to face any issues, please reach out to us at

Love this app!

This app is great! Makes my life so much easier because I almost always have my phone in hand so I can just badge in when I get to work instead of having to find my keycard. 👍🏼

Apple Watch problem

The app works great on my iPhone but doesn’t work at all on my Apple Watch and I can’t find any instructions to help me troubleshoot.
