Not ready for prime time

I love the company and I love the niche they are trying to fill. I understand that the IOS limitations prevent the application to work the way it is intended and it breaks my heart.

It is just wildly unreliable. If you don’t have the app running in the foreground, then it won’t unlock the workstation. I should be able to let the app run in the background and unlock the workstation.
