I've set it up now just to check. The initial setup is online. All you need to do is make an account (verified via an emailed code), log in, and enter your surname and 2 numbers on the physical license and it will download the information. You can then go offline and still view it. There's a QR code which doesn't directly contain a URL or anything, so I'm not sure if the police need to be online to validate using it, I didn't look into it much. It also says the last refresh time and pulling down will refresh the information however this fails when offline (the app doesn't seem to check network availability, it just tries to load forever). So I'm not sure if this is a problem. It also seems to be really poorly optimised on Android, the UI is basically unresponsive on my phone and slows the whole system down. Regardless needing to carry the real license as a backup is a problem, since it sounds like they'll make no concessions if you left it at home for a short drive and your phone dies.
