Who each one suits
jtx Board

- Nextcloud, Fastmail or Radicale users who want journals too

OpenTodoList
- People who want tasks and notes kept as files they control
- Nextcloud and ownCloud users on both phone and desktop
- Shopping lists, household tasks and recipes in one app
Worth knowing
jtx Board
- Android only: the vendor's terms say the app is currently available on Android, and no iOS, desktop or web version is listed.
- Sync needs the separate DAVx5 app and a server that accepts VJOURNAL; the compatibility list marks iCloud, Posteo, Ionos and Infomaniak as not supporting it.
- In the Google Play version, editing entries in remote collections is part of the paid Pro upgrade.
- Google Play lists in-app purchases at $0.99 to $3.49 per item without naming them, so the exact Pro price is not shown; the app's code treats Pro as a one-time purchase.
OpenTodoList
- There is no hosted sync service: using a library on several devices needs a Nextcloud, ownCloud, WebDAV or Dropbox account, or an outside sync tool.
- No web version is listed; it runs as an installed app on Android, iOS, Linux, macOS and Windows.
- The AI integration currently covers recipe import only, and an online provider needs the user's own API key, which may carry separate costs.
Key features
jtx Board
- Journals, notes and tasks in one app
- Journals hold dated entries such as meeting minutes or a diary, notes hold memos without a date, and tasks carry due dates, subtasks and a progress value.
- Linked entries
- Tasks can be attached to a journal or a note, and any entry can take a comment or an audio comment, so follow-ups stay with the minutes they came from.
- iCalendar standard format
- Journals and notes are stored as VJOURNAL components and tasks as VTODO components under RFC 5545, so other apps and servers that follow the standard can read them.
- CalDAV sync through DAVx5
- The separate DAVx5 app syncs entries with a CalDAV server the user picks, including a self-run one. Infomaniak's kSync, a fork of DAVx5, also works.
- Local storage and offline use
- Entries are stored on the device and the app works without an internet connection; syncing is optional.
- Recurrence, alarms and locations
- Entries can recur daily, weekly, monthly or yearly, raise alarm notifications and carry a map location. Geofence notifications are in the Google Play version only.
OpenTodoList
- Libraries
- A library is a container for todo lists, notes, images and recipes, so related items stay together. Each library can be given its own color.
- Todo lists, todos and tasks
- A todo list holds todos, and each todo can be broken into tasks. Items can have due dates and recurrence, and a schedule view shows what is due across all libraries.
- Notes with pages
- A note is a text container that can take additional pages, which turns it into a small notebook. Images are separate items with a title and description.
- File-based storage
- Each library is a normal directory of files on disk, so it can be backed up, inspected, or synced with an outside tool the user already trusts.
- Sync through your own storage
- Libraries sync through Nextcloud, ownCloud, generic WebDAV servers or Dropbox. Sync is chosen per library, and a local library is never copied to a server.
- Recipes with optional AI import
- Recipes hold ingredients, steps, notes and yield. An optional AI action turns pasted text or a web page into a recipe, using Apple's on-device model or an OpenAI-compatible provider.
