WWI timeline - WWI history

I only gave it four stars because it was a very easy app to put together (literally a simple time-line) and did not require much originality. It lists all pertinent and important time features leading up and during World War I. But then again, I do not need to know every time Archduke Ferdinand used the bathroom. Also has a very good reference material reference from the timeline that makes it a very very good report writing tool. Very good app for a World War One timeline.
