Good app. Needs iPhone X Support

Good app but needs iPhone X support along with multiple people in charge of one lock.

Works great as is. When can I have an Apple Watch app also?

Software works great for our small business. Easy to manage and audit who comes in and when. Adding/removing users is simple. I would like an Apple Watch app option to open locks.


Needs to be updated or removed from App Store

It is letterboxed on my Pro Max iPhone.
It does not integrate with the iOS password management. Not sure how this app got approved by the App Store.
