Tasks.org is a free and open source to-do and task management app for Android with a focus on privacy and synchronisation. It descends from the source code of Astrid, a popular productivity app discontinued in 2013, and offers powerful recurring tasks, subtasks, location reminders and custom filters — all without ads or data sharing.

Key Features

• Open source — Licensed under GPL-3.0, with no ads and no data ever shared with third parties.
• Flexible synchronisation — Sync with Tasks.org Cloud, Google Tasks, DAVx5, CalDAV, EteSync, DecSync CC, or work completely offline.
• Recurring tasks — Set up flexible and customisable recurrence rules for repetitive chores.
• Subtasks — Organise work with nested, collapsible subtasks of unlimited depth.
• Location reminders — Get reminders based on arriving at or leaving a specific location.
• Filters & search — Find tasks quickly with powerful filtering and full-text search.
• Widgets & Wear OS — Customisable home-screen widgets and a Wear OS app with watch-face complications.
• Backups — Automatic backups to internal storage, Google Drive or the Android backup service.

Why Use Tasks.org?

Tasks.org is ideal for privacy-minded Android users who want a capable, ad-free task manager that syncs with self-hosted CalDAV servers, EteSync or plain offline storage. Its synchronisation is a full-featured Pro capability that is bundled unlocked in the F-Droid build, keeping the entire experience open source.

Use Cases

• Managing personal to-do lists with recurring tasks and location-based reminders on Android.
• Syncing tasks with a self-hosted CalDAV server (such as Radicale), Nextcloud Tasks or EteSync for end-to-end encrypted sync.
• Replacing a proprietary to-do app with an open source, ad-free alternative that works offline.
