What is jtx Board?

jtx Board is an open-source Android app that keeps journals, notes and tasks together and lets them be linked, for example tasks attached to meeting minutes. Entries follow the iCalendar standard (VJOURNAL and VTODO), are stored on the device and can sync with a CalDAV server of the user's choice through the separate DAVx5 app. The Google Play version is free with a paid Pro upgrade, and an open-source edition is published on F-Droid.

jtx Board has a free plan. Paid plans start at $0.99 to $3.49 per item, in-app purchase on Google Play (basis not shown). See every plan

Good for

  • Android users who sync tasks with their own CalDAV server
  • Nextcloud, Fastmail or Radicale users who want journals too
  • Keeping meeting minutes and their follow-up tasks together

Worth knowing

  • 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.

Key features

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.
