Ive been using this app for over a year and have found it to be very reliable. On miserable rainy days like today, I can sit in my house and remain dry as I watch the app track my bus. Its great!
One disappointment is that the app has not yet begun tracking the new bus line (7Y) that began serving my neighborhood a few months back. Hopefully that will be addressed in the next update. Otherwise it has been a very reliable and I would highly recommend it.
