Type n Walk ★★☆☆☆ ($.99 / App Store) for the iPhone is a text writing app designed specifically for typing while walking. A few minutes in a crowded city will reveal how many people walk dangerously with their head down looking at their smartphone typing away. Type n Walk in theory should alleviate this modern epidemic by having a transparent canvas - it looks like your looking through the camera while typing so you can see your path in front of you. It can compose and send SMS, emails and Tweets or simply copy the text to paste for later use. Two major missing elements keep this from being a 4 star app; the keyboard itself is completely opaque and there is no landscape mode.
