Quick answer

Tasks, notes and calendar over CalDAV — or local-only on your phone.

TaskDav is a free and open-source Android app for tasks, notes, and calendar events.

Use it fully offline on the device, or sync with your own CalDAV server (Radicale, Nextcloud, Baïkal, and similar). Credentials stay encrypted on the phone. There are no ads, analytics, crash trackers, or Google Play Services.

Features: • Offline-first tasks (VTODO), notes (VJOURNAL), and events (VEVENT) • Nested tasks and nestable categories • Tags, due dates, priorities, and optional linked calendar events • Home dashboard with overdue, today, and upcoming items • Day / week / month / year / list calendar views • Home-screen widgets for today, week/month agenda, tasks, and notes • Themes from a brand color; UI in English, Spanish, and Italian • Share as text or .ics; optional phone-calendar mirror/import • Works alongside DAVx⁵ on the same account

How to install

  1. Download the APK from the button at the top of this page.
  2. Allow “Install unknown apps” for your browser or file manager only, not for every app.
  3. Open the downloaded file and confirm the installation.
  4. If installation fails with “App not installed,” remove an earlier build of the same app first. A signature conflict is the usual cause.

  • Files are scanned for malware on every update.
  • The permissions each app requests are listed on its own page.
  • Read the full safety policy for how we test, flag, and delist files.
