I have been using a similar app in Seattle called Seattle Bus. It tells me interactively if my bus is late and by how many minutes by using the gps on the buses. This LA metro app is disappointing in comparison and I am surprised the reviews gave so many stars. All this is is a light rail schedule, which you could have written in a piece of paper for your station and put in your pocket. You dont even need an iPhone! The info for this ad did say that you can use this program offline, but I didnt know that was what the developer meant. To be fair I should point out that it does have google map for locating your station, but it is not integrated into the app. So why use google map within this app? It cannot give me directions to go from A to B unless these are stations that I already know. Then I dont need directions.
In addition, the LA light rail system is quite limited and so there is not much information that is in here. If I am trying, for example, to go from Union Station to Burbank airport. You would type in From Union Station and To Bur... It would say it cannot find anything. I guess Silver Line is not yet included although I can see it in the metro map above the doors in the light rail I am riding.
