Once you've got the hang of it it's easy but it's not always reliable. I can't manually correct my shift times and sometimes the QR scanner doesn't work so I'm not checked in/out. It's especially tricky for first timers and the elderly so not a very good app for a test center unless you've done it a few times or are a quick learner.

It's a user friendly app to use, eventhough I'm not a German speaking person but have been able to use it for regular testing. Kudos to everyone involves in the setting up of this app.

App logged out and doesn't accept any password anymore. Tried to reinstall it with the same result. Absolutely useless..
