The most frustrating system I've ever used. My apt. building switched to using this app to unlock the doors and it takes, at minimum, 15-30 seconds to unlock the door. I frequently have to restart my phone before I'm able to get into the building, causing me to be outside in the cold. I've also gotten logged out multiple times, requiring me to email building management to get a verification code to be able to log back in. If you or your business is looking for a reliable system, look elsewhere.

Even after giving the app all of the possible permissions and turning off paused activity of unused on android, I can't keep a credential for more than 3ish days of inactivity before being revoked. This is in comparison to others given the credential to the same room as me and having it for months or even a year after inactivity. Very annoying, a key would be better.

comically bad. regularly fails to find doors, slow to open, and sometimes drops authorizations spontaneously.

What’s new

In this version we have added additional controls for the distance used for the Phone as a badge feature. This new ability allows the user to set the distance to be short. Medium. Long. This, along with cyber security hardening, standard defect resolutions and Android 16 OS support changes.
