UberWriter  

With UberWriter (5 $) it’s simple to write beautiful documents in Markdown.
First of all, it doesn’t give you any preferences. Huh? Yes, I might add some in the future, but for now, it’s kept simple on purpose: It should faciliate your writing and not distract you from your task by searching for the right font (the right font in this case is obviously Ubuntu Mono) or font colors, headline sizes and so on.

It offers a «distraction free» mode (focus mode) that highlights your last sentence and gives you a typewriter-esque feel. UberWriter offers out of the box spellcheck, and a very clean interface. There is a fullscreen mode which gives you a whole, white page.

And the best: Inline Markdown highlighting, because it’s great. Please watch the screencast to see it in action, because words fail to describe it. It’s a remarkable simple idea but works very well.
