jtx Board suits people who want journals, notes and to-dos in one place and who prefer to store them on their own CalDAV server. It comes from Techbee e.U., costs nothing, shows no ads and is released under the GPL-3.0-only licence. Version 2.17.03.ose needs Android 7.0 and takes up 8.5 MB.
VJournal is the idea behind the app
The app is built around the iCalendar standard, RFC-5545. Most calendar apps handle VEvent, some handle VTodo, and VJournal is almost unused. jtx Board uses it on purpose, and the developer says it wants to revive that component.
In practice the split is simple. A VJournal with a start date becomes a journal entry, and one without a start date is treated as a note. Tasks use VTodo, which can carry a start, a due date, a completed date, a progress value and a completed status.
Because the data follows the standard, it is not tied to one provider. Journals cannot have an end date or a duration, which is a limit of the VJournal definition itself.
Meeting minutes linked to tasks, synced through DAVx5
A typical session starts with one kind of entry and branches out. For example, write meeting minutes as a journal or note, then create tasks and link them to those minutes. Notes, journals and tasks stay in one app instead of three.
Sync runs through DAVx5, which acts as the sync adapter between the phone and a CalDAV server. You choose the provider, and a local server works too. DAVx5 is a separate app and has to be obtained on its own.
Import and export of .ics files is a planned feature.
Where it sits next to Fossify Calendar and Google Calendar
Fossify Calendar, Google Calendar, Period Calendar Period Tracker, Hebrew Calendar, Persian Calendar and Samsung Calendar sit in the same calendar category. Nothing here describes their features, so a point-by-point comparison would be guesswork.
What is clear is where jtx Board puts its weight. It is tagged for notes and tasks alongside calendar and agenda use, it is open source, and it carries no ads. If you mainly want a plain event calendar, the alternatives are probably the first place to look. If you want your VJournal and VTodo entries kept in an open format you control, that narrower purpose is a good reason to choose this app.
