I found the Snapper app on my phone really handy. I can check the balance of my Hop card and even top up using my credit card if I'm short of funds (without any fees!)
I've finally been given the heads up that AT Hop is to be used on my routes starting from next week. Anyone know if they're going to have any Android functionality? Ideally, something similar to the Snapper App that will let me read/topup my AT Hop card? Even better would be if I could use my phone as my bus card using NFC or whatever.
Otherwise, at least I can top up the AT Hop card online, I suppose.
