I buy my passes on the app, and its so easy to buy AND use. Ive had a panic moment or two when my phone is almost dead, but thats on me. And I love the trip planner. Ive even helped bewildered people at bus stops by using this app by using the trip planner for them. My only tiny gripe is I cant use it while on a call, which doesnt happen often, and I can just hang up use it quickly, then call back. Overall, Ive NEVER had an issue.
