Apostrophe (text editor)

Apostrophe (formerly known as UberWriter) is an open-source, minimalist Markdown text editor, developed by Wolf Vollprecht. It was originally created for the Ubuntu App Showdown, and has since received recognition as one of the Top 10 Ubuntu Apps of 2012.

Wolf Vollprecht credited the Mac application iA Writer as being the inspiration for UberWriter, and has expressed his wish to see the two programs become compatible:

• Clean user interface
• A focus mode, which greys out all but the sentence you are actively working on
• Fullscreen mode
• Markdown syntax highlighting
• Live word and character counting
• Live preview mode
• Out-of-the-box math support
• Can export Markdown to OpenDocument (ODF), PDF, EPUB, Rich Text Format (RTF), HTML, LaTeX, and MediaWiki Markup
