The busses in my area have a service whereby you text in a number corresponding to a bus stop and they send back a text with the times that the next busses will be passing by. What the STO Bus Finder does, then, is that it sends the text for you and then recieves and formats the reply.
The main feature is that you can store favourite stops so that with only a couple taps you can know when the next bus to work leaves, or how soon you would have to leave school to catch the next bus home.
I mostly made this app for my own convenience, and use it frequently, but given it's usefulness I decided to give others the opportunity to have it.
The STO Bus Finder can be found on the Google Play Store.
