QOwnNotes is a free open source (GPL) plain-text notepad with markdown support and todo list manager for GNU/Linux, MacOS and Windows, that (optionally) works together with the notes application of ownCloud.
Not much different from other notes applications, but can be a decent choice to use.
In case you’re not familiar with ownCloud, this is a free software alternative to proprietary web services such as Dropbox, Google Drive, and others, which can be installed on your own server.
It comes with a web interface that provides access to file management, calendar, image gallery, music player, document viewer, and much more. The developers also provide desktop sync clients, as well as mobile apps.
As for the QOwnNotes note taking features, the app supports Markdown (with a built-in Markdown preview mode), tagging notes, searching in tags and notes, adding links to notes, and inserting images.
The application user interface is customizable, allowing you to increase or decrease the font size, toggle panes (Markdown preview, note edit and tag panes), and more. A distraction-free mode is also available.
If previously available Simplenote, then QOwnNotes is the same thing, but has more interesting features.
