It really isn't. It's next to impossible to navigate to the exact schedule you want so if you ever stumble upon it you better favorite it. I luckily no longer need it for my commute but earlier this year there was a good stretch of two months where the app wasn't displaying tickets at least once a week right during the morning rush so I ended up having to pay because they couldn't be bothered to give their drivers a heads up that there were problems with the app.
