Used to be great. I have used this app for years, and recommended it to everyone I know trying to get around New York. However, in the last month or so since the latest update, it crashes on me constantly while I'm on trips. Unless I'm looking at this phone screen the whole time I don't know when I have stops coming up because it will just crash with no notification and I'll go to check it but it's off. On two occasions now I have missed stops going to places I was unfamiliar with.
