I just release a new iOS app: Fast Keyboard. (I am the developer) It is a text editor with an addition two-row keyboard to make typing faster. On top of the standard iOS keyboard, you can have numbers, symbols, unicode symbols, frequently used words, and even email/article templates. Then you don't need to constantly switch between the letter keyboard and the number keyboard. And you can type with fancy symbols: π,☆,÷,♥,♬ and so on. And the text you wrote links to Dropbox, Facebook, and Tumblr. And there are some advanced functions, like • Left and right arrow keys to move the cursor • Search a word • Word, line, character counting • Key statistics It works on iPhone, iPad and iPod touch. If you have any questions or comments, please feel free to let me know. Thanks a lot.
