OK, you got me! This is not an app but definitely an extensive and exhaustive look of text editors for iOS. If you do some writing on your iPad, iPhone or iPod Touch then this is definitely worth the look. The information was compiled on a public Google Doc and the editor is going to go through this list as time permits to check its accuracy. You can also add an app or a correction. There is a massive chart comparing all the features of each app and below the chart there is detailed information and screen shots of specific apps. Here are a few (this is a big page people) images to give you an idea of how thorough this compilation is. You can find it the list in its glorious entirety here.
