### 1/5 — Your update messes up

*2026-04-09, version 2.1*

UPDATE:  the update did not lose my card what it did it lost the information and description that was on each card.  Both cards are the identical.  Before it had information about the card.  Like the one was the diagnostics card the other the entry card.  Further on the display it is just a white band on the bottom of the screen.  Leaving the rest of the review as is.  

I am giving a one star review to hopefully get your attention.  Been using your app for some time.  It works OK but not how we all thought. This updated has problems.  First it showed up to replace the old one.  And it LOST the vats we use to adjust the readers.  And of course cannot re-enter it.  To get a new one is going to cost me. Then we have our unlock time set to five minutes.  Guess what the display now shows 00:300. So no one tested it!  Coding error.  Now here is what is never worked although you said you fixed it. 

— So it runs in background have it permission.  Does nothing.  I stand by the reader and nothing!
— Well if I have the app up but phone closed.  Again nothing. 
— try if I have the app up but not displayed phone open.  Nothing. 
— it only works if the app is shown on the screen.  BUT it needs to be counting down after pressing the button.  Otherwise you just stand there. 

Hopefully whoever there who broke the display and lost my card can fix that. It looks very unprofessional to see 00:500 for the court down.

### 1/5 — Zero app support - access control is nontransferable

*2025-10-02, version 1.0.2*

Beyond basic functionality, this app is far from robust. There is no method to remove access control credentials that works (it just errors out citing backend issues) and the credentials are non-transferable between mobile devices even if the registered phone number is the same (ie when you get a new phone you can’t migrate your existing credentials to it). Worst of all, some brand new credentials that had never been activated did not work (and each license/credentials costs $$ to purchase) and when I tried reaching out to support via the phone line on the app, I got a dead end prerecorded message telling me to go find the commercial reseller that sold this subpar solution to my original builder (what?!?!). Unless they resolve credentials transfer issues or offer some kind of app support, I recommend that any organization considering purchasing mobile access control technology stay far far away from this one. There’s no way to get anyone at Linear/Nice to help when things go wrong.

### 2/5 — Can’t Add to Wallet or Apple Watch

*2024-07-31, version 1.0.2*

Would be nice to add to wallet and Apple Watch. 

Doesn’t reach far and is very slow.
