As an info app, Wikipedia's official app looks just like its web version, which is clean, simple and easy to read. However, prior to being digitized, encyclopedias were bound as beautiful book editions, embodying wisdom, refinement, culture and style.
Raureif's das Referenz: Wikipedia iPad app is an alternative to using Wikipedia's basic interface and instead, provides you with book-like layouts for easy reading. Although the iPad app borrows the vintage look and feel of an old library book, the app isn't all old fashioned and it includes big pictures, an intuitive page flipping gesture and other impressive details—at first, articles are all black and white, but interacting with the page will bring them to life with color.
The app is free to download but it does include ads, which can be removed for a cost of $3.
