Info.graphics is nice if you want to find and share premade and pubished info graphics. THere are some good ones, but the collection is small, I thought. There was no way to create your own either. The biggest flaw was that the source links were not live. I wanted more info on one interesting graphic but I could barely read the link. That lack of reference makes me nervous. I want to be able to check sources!
I will have a look at the other apps later this summer. A good info graphic app would be a big help in my library.
