Tasks.org
Free Our pickOpen-source Android to-dos done right — reminders, lists, widgets, and it syncs over open CalDAV instead of a company's cloud.
5 private options, our pick first. Every download link goes straight to the source — F-Droid, the developer's GitHub releases (one tap into Obtainium), the Play listing you can install anonymously through Aurora Store, or the official site. None of these are affiliate links. Updated October 2026.
These Google Tasks alternatives are for to-do lists and reminders on Android that don't depend on a Google account. Tasks.org is the main pick: open source, with widgets and reminders, and sync over open CalDAV. jtx Board and Super Productivity cover journals and time tracking.
The trade-off is setup. Tasks inside Gmail and Calendar just appear, while a private setup needs a CalDAV server, such as Nextcloud or a hosted provider, if you want sync across devices. If you only use one phone, you can replace Google Tasks in 2026 with no account at all.

Open-source Android to-dos done right — reminders, lists, widgets, and it syncs over open CalDAV instead of a company's cloud.

Honestly? A lot of degooglers discover a notes app or paper covers it.

Journals, notes and tasks synced over CalDAV — a good fit with DAVx⁵ and Nextcloud.

To-dos with time tracking and focus timers. Open source, works offline, optional sync.
No. Tasks.org works fully offline with local lists, and reminders and widgets still work without any account. You only need a server if you want the same lists on other devices. Options include a self-hosted Nextcloud with Nextcloud Tasks, a hosted CalDAV provider, or the developer's own Tasks.org sync service.
Yes, through the server rather than the app. On Nextcloud, a shared task list syncs over CalDAV to everyone who has access, and each person can use Tasks.org, jtx Board or another CalDAV app. Shared lists depend on your server's sharing features, so check those before you promise the family a shared grocery list.
That link doesn't survive the move. Google Tasks can point back to an email in Gmail, but a CalDAV task is a plain item with a title, notes, dates and reminders. If a task depends on a message, paste the key details or the sender's name into the task notes before you leave Google.
