jtx Board

Journals, notes & tasks in one app — built on the iCalendar standard and synced with the CalDAV server of your choice.

Tip

Also by Techbee: Spectacled – open, standards-based journals, notes and tasks for Android, iOS, Web and Desktop, syncing directly over CalDAV without DAVx5. Find out more at spectacled.techbee.at.

Get the most out of journals, notes & tasks

Take the iCalendar standard to the next level: combine journals (VJOURNAL), notes (VJOURNAL) and tasks (VTODO) in one app and use DAVx5 to synchronize your entries with the CalDAV server of your choice!

iCal standard compliant

Using the iCal standard ensures compatibility and interoperability with other apps and services, independent of a dedicated provider or infrastructure. Journals and notes are compliant with the definition of the VJOURNAL component, tasks are compliant with the VTODO component. You can also import and export your entries as .ics files.

Combine journals, notes & tasks

Instead of using separate apps for journals, notes & tasks, you can manage them all in one place, then combine and link them to each other, e.g. create meeting minutes and link your tasks to them.

Sync with DAVx5

Synchronize your entries with any compatible CalDAV server by using DAVx5. With DAVx5 you are free to choose your preferred CalDAV provider; you can even use your own local server to store and synchronize your data. Note: DAVx5 is an independent app and must be acquired separately.

Features

Building from source

Requirements: JDK 21 and the Android SDK. jtx Board runs on Android 7.0 (API 24) and newer.

git clone https://github.com/TechbeeAT/jtxBoard.git
cd jtxBoard
./gradlew assembleOseDebug

The APK is written to app/build/outputs/apk/ose/debug/.

Flavors

jtx Board provides the following flavors:

• gplay is the flavor for the Google Play Store. It comes in a standard and a pro version. The pro version is paid and enables editing options for remote entries.
• ose is the open source edition. If you would like to build the app from source, this is the recommended flavor. It contains only open source libraries. Instead of an in-app purchase, this flavor shows an additional page for donations. As Google Maps is not open source, the ose flavor uses OpenStreetMap.

Note

The huawei (Huawei AppGallery), amazon (Amazon Appstore) and generic flavors are deprecated and no longer maintained.
