iBartNow

The iBartNow for Android will help you find the train departure information from any station within the BART system. It's great for commuting, especially when you are trying to catch a train and not exactly sure when it should arrive at your station. I also use it from time to time to catch a train in a opposite direction and get a seat on my train a few stops earlier - for those experienced BART riders, you know what I mean.
This version has BART map as well, though it might be showing small on some phones.
