It's average. It kinda works sometimes. The interface isn't great but it's kinda functional. I don't trust the app because it only notifies me maybe 50% of the time. Yes, I know how to configure the app and handle notifications, I'm "tech-savvy". That being said, the issue could be with the bus company, i.e. Yhe app isn't getting accurate information from the source. But that shouldn't be my problem. And the interface looks dated, reminds of very early Android apps.
