Iotas aims to provide distraction-free note taking via its mobile-first design.

Featuring

• Optional speedy sync with Nextcloud Notes
• Offline note editing, syncing when back online
• Category editing and filtering
• Favorites
• Spell checking
• Search within the collection or individual notes
• Focus mode and optional hiding of the editor header and formatting bars
• In preview: export to PDF, ODT and HTML
• A convergent design, seeing Iotas as at home on desktop as mobile
• Search from GNOME Shell
• Note backup and restoration (from CLI, for using without sync)
• The ability to change font size and toggle monospace style

Writing in markdown is supported but optional, providing

• Formatting via toolbar and shortcuts
• Syntax highlighting with themes
• A formatted view
• The ability to check off task lists from the formatted view

Slightly more technical details, for those into that type of thing

• Nextcloud Notes sync is via the REST API, not WebDAV, which makes it snappy
• There's basic sync conflict detection
• Notes are constantly saved
• Large note collections are partially loaded to quicken startup
• Notes are stored in SQLite, providing for fast search (FTS) without reinventing the wheel. Plain files can be retrieved by making a backup (CLI).
