Practically useless

You have to be connected to the internet to access your ticket. No internet, no ticket. This put me in a bad situation on the train when the controller asked to see my ticket in the train as I had no access to the internet.

Also, you have to sign in each time you use the app. If you have a The Card number you have to look it up and enter it for each use.

Terrible.
