GitJournal

• pretty easy setup and syncing if one has at least a slight knowledge how git (or at least ssh) works - amazing
• young project, but opensource on github (not too difficult to contribute)
• only needs some markdown editor to be used on desktop
• on my personal wishlist was: access to files on android user space (optional, configurable)
• wishing a description of the markdown options used and understood or ignored by this app (maybe simply as a reference to a well-known platftorm using markdown - like gitlab or github)

It doesn't bind you to a platform/service/app. Runs without any lag. Note creation and Git syncing simply work without any difficult, yet you can configure automatic file names and titles, creation and modified dates etc (if you want). Read other comments for other features. It's fantastic yet simple.

As Got Journal is an open source software and powered by git. You can trust but its not made by the own company of git. Its made by a developer and had the access to connect to git softwares and web applications.

A clean simple way to use GitHub as a storage mechanism for a markdown-based journal. Makes task lists, notes and daily journals easy, and handles all the git mechanics invisibly. Perfect for syncing between several platforms.

Very responsive to feature requests and bug reports.
