Sadly it doesn't address any of the problems with cabs in Toronto.
1. Cabs won't take credit cards by claiming "the machine is broken" when it's not, presumably so that they can avoid reporting tips or fees, or they might just skim your card.
2. Cabs are too expensive.
3. Cabs might not even take you if they figure the ride isn't worth it.
This app doesn't allow you to pay, so doesn't help 1. It actually make 2 worse by charging you $2 just to "hail" a cab with it. I mean, seriously? And it doesn't help with 3 either.
