Markdown Guide

Using Markdown in Day One

Day One can convert text written with Markdown into rich text. Conversion will happen in real-time as it is typed. Or use a Code Block to write entire sections using Markdown. Additional formatting tools can be found int he following two guides: iOS, macOS.

When using a code block, click/tap the code icon at the bottom right to switch between Edit and Read modes.

A code block may also be initiated by typing 3 back ticks and tap the Spacebar.

Markdown Information

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.
