Markdown, created by John Gruber of Daring Fireball, is the technology we chose to use to allow rich text within Day One journal entries. Markdown allows italic and bold, along with several other simple formatting options that can be written using plain text and display properly in Read views. Markdown syntax is available in Day One and is toggled On by default.
Day One for Android does not have a Markdown toolbar, but the Markdown syntax featured on this page can be manually typed out to format text.
Day One takes a similar approach to Markdown as GitHub. See GitHub Flavored Markdown.
The best way to see how Markdown formatting works in Day One is to refer to these sample entries:
