About

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).
