Why OpenCards ?

1. Practice too soon and you waste your time. Practice too late and you've forgotten the material and have to relearn it. OpenCards will choose just the right moment to let you review the things you want to keep in mind. Based on the idea of Ebbinghaus that the knowledge decays along a negative exponential curve, OpenCards will present facts for review right before you will have forgotten them. OpenCards predicts your memorization performance in order to maximize knowledge retention. Thereby it minimizes your time investment necessary to memorize tens, hundreds, thousands or even millions of facts. (... ok, forget about the millions )
   
2. There are many flashcard learning applications available. Some of them implement fancy learning techniques, some of them look very polished, but almost all of them lack of one essential feature: Flexible, intuitive flashcard creation. In most cases they support simple text cards only. Here we try to overcome this limitation by just plugging well-established learning methods into one of the best free office applications available: OpenOffice Impress. Just give it try, you'll love it !!!
3. It's free as free beer, open source and platform-independent
