Useless 80% of the time.
20% of the time (when everything is working) it's SO HELPFUL. I wish it was reliable. My daughter is in high school and half the year she is waiting in the cold and dark for the bus. This is terrible when the bus is usually 15 minutes late but surprise! sometimes on time or even up to 10 minutes early! Knowing where the bus is ~15 minutes before scheduled pickup allows her to stay home where it's light and warm a little longer. We can get her to the stop at the perfect time. It works like that about one day a week. The other 4 days of the week the app only says "waiting to identify bus" and never changes. So she has to get to the bus stop 10 minutes earlier than the schedule says and in all likelihood then wait nearly 30 minutes for the 15 minute late bus when it's cold and dark outside. It's sad and depressing for these poor kids that are already struggling. A system/app that is reliable would be make their very early mornings just a little better.
