Not the best but it works

In my opinion this app works. But not all the time, for example I was with my mom trying to catch the 20 and she was using this app to look at the bus times, it said no arrival times so we started to walk up, at our confusion we noticed the bus drive by and then we had to walk 20 minutes to get home!

Not the best app but it works about OnTime App for London Transit, v2.0.17
