Iotas aims to provide distraction-free note taking via its mobile-first design.
The software lets you backup and restores notes with Nextcloud Notes. But you can also perform your own backups from the command-line.
This is free and open source software.
Key Features
- Optional speedy sync with Nextcloud Notes.
- Offline note editing, syncing when back online.
- Category editing and filtering.
- Favourites.
- Spell checking.
- Search within the collection or individual notes.
- Focus mode and an option to hide the editor header bar.
- 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.
- Supports Markdown:
- Formatting via toolbar and shortcuts.
- Syntax highlighting with themes.
- Formatted render view.
- Check off task lists from the rendered markdown.
- Nextcloud Notes sync is via the REST API, not WebDAV.
- 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).
