One Bus Away is simply brilliant. I have downloaded the One Bus Away app since its launch last year. 95% of the time it is pretty accurate. I absolutely love this app and have convinced many friends to download the app as well. It is also convenient when I am away from my phone, I can check out the bus routes and real time online. However, I cannot give it a 5-star just yet. There were definitely times here and there where the service was completely off. If you use the app, you cannot completely trust it. Make sure you double or even triple check the stop and real time. One time it said my bus would be 27 minutes late. The next minute I checked it said 3 minutes late. Later on again, it sad on time. Then I checked again it said 20 minutes late. I was really confused. Eventually the bus actually came right on time. I remember during the snow days it was pretty messed up. It would mark something like«160 minutes» late for the bus. Although it would still not be accurate because the buses would come and stop on the bottom of a hill. But then, many things were pretty messed up during heavy snow days in Seattle. In general, very useful app. It is especially useful if you need to get somewhere by bus for an appointment and give others advance notice when your bus runs late. If a bus runs really late, I either choose an alternative route or quickly run errands. In addition, bus 48 is consistently late so this app lets me know how long I still have to wait at the bus stop. After all, love this app and One Bus Away!
