It syncs via Tasks.org's own service, Google Tasks, CalDAV/DAVx5, EteSync (end-to-end encrypted), or DecSync CC, making it compatible with Outlook, Thunderbird, and Apple Reminders. It works fully offline and never shares your data. - **How it works**: You create tasks and organize them into lists with tags, due dates, and reminders, nesting subtasks as needed and sorting or filtering the view. Connect an account (Google Tasks, a CalDAV server, or EteSync) to sync tasks across devices, including a desktop app (alpha) and Pebble smartwatch support. ## Profile - **License**: GPL-3.0 (verified 2026-07-12) - **Pricing model**: Freemium (verified 2026-07-12) - **Starts at**: $0.99/year (verified 2026-07-12) - **Platforms**: Android - **Status**: active (verified 2026-07-12) ## Ranked alternatives | # | App | Alt Score | Licence | Platforms | |---|-----|-----------|---------|-----------| | 1 | [Todoist](https://altcatalog.com/alternatives/todoist.md) | 87 | ? | Windows, macOS, Linux, iOS | | 2 | [TickTick](https://altcatalog.com/alternatives/ticktick.md) | 83 | Proprietary | Windows, macOS, Linux, iOS | | 3 | [Amazing Marvin](https://altcatalog.com/alternatives/amazing-marvin.md) | 79 | Proprietary | Windows, macOS, Linux, iOS | | 4 | [Any.do](https://altcatalog.com/alternatives/anydo.md) | 79 | Proprietary | Windows, macOS, iOS, Android | | 5 | [Remember The Milk](https://altcatalog.com/alternatives/remember-the-milk.md) | 79 | Proprietary | Web, Windows, macOS, Linux | | 6 | [2Do](https://altcatalog.com/alternatives/2do.md) | 75 | Proprietary | iOS, macOS, Android | | 7 | [Akiflow](https://altcatalog.com/alternatives/akiflow.md) | 75 | Proprietary | Windows, macOS, iOS, Android | | 8 | [OmniFocus](https://altcatalog.com/alternatives/omnifocus.md) | 71 | Proprietary | macOS, iOS, Web | | 9 | [Super Productivity](https://altcatalog.com/alternatives/super-productivity.md) | 67 | MIT | Windows, macOS, Linux, Android | | 10 | [Motion](https://altcatalog.com/alternatives/motion.md) | 63 | Proprietary | Windows, macOS, iOS, Android | | 11 | [Sunsama](https://altcatalog.com/alternatives/sunsama.md) | 63 | Proprietary | Windows, macOS, Linux, iOS | | 12 | [Things](https://altcatalog.com/alternatives/things.md) | 63 | Proprietary | macOS, iOS | | 13 | [Microsoft To Do](https://altcatalog.com/alternatives/microsoft-to-do.md) | 59 | Proprietary | Windows, iOS, Android, Web | | 14 | [Vikunja](https://altcatalog.com/alternatives/vikunja.md) | 59 | AGPL-3.0 | Windows, macOS, Linux, Android | | 15 | [TeuxDeux](https://altcatalog.com/alternatives/teuxdeux.md) | 50 | Proprietary | Web, iOS, Android | | 16 | [Google Tasks](https://altcatalog.com/alternatives/google-tasks.md) | 46 | Proprietary | Web, iOS, Android | | 17 | [Nirvana](https://altcatalog.com/alternatives/nirvana.md) | 42 | Proprietary | Web, iOS, Android, macOS | | 18 | [Structured](https://altcatalog.com/alternatives/structured.md) | 38 | Proprietary | iOS, macOS, Android, Web | | 19 | [Taskwarrior](https://altcatalog.com/alternatives/taskwarrior.md) | 38 | MIT | Windows, macOS, Linux | Alt Score = Verified coverage (90%) + Visibility (10%).
