Suggestion
I propose adding a new section dedicated to recommending to-do list managers and task management tools. While some of the currently recommended notebook applications—such as Standard Notes, Joplin, and Notesnook—offer basic to-do list functionalities (with Notesnook even providing reminders), they do not deliver the full range of capabilities provided by dedicated task management tools. The same can be said for tools like Obsidian and Anytype, which are currently not recommended. Additionally, there is Org Mode which is not suitable for everyone due to its UI and Linux exclusivity.
Criteria
The criteria for task managers could be based on those used for notebook applications but with some adjustments. Specifically, we might need to remove the strict requirement for tools to be open-source due to the scarcity of such options in this category. Instead, we could require that these tools be either open-source or have undergone a third-party security audit to ensure user privacy.
Software
Some cross-platform solutions I am aware of include Legend, Lunatask, Illumtori, and Everdo. These applications are E2EE but proprietary—though Legend is partially open-source.
For users within the Apple ecosystem, OmniFocus (which is E2EE and audited) and Apple’s Reminders (which becomes E2EE when used with ADP) are notable options.
On Android, there’s Tasks.org, an open-source application that is not E2EE unless used in conjunction with EteSync.
On Linux there is Todo.txt and tools based on it such as Sleek.
For those interested in self-hosted solutions, Vikunja and OpenProject are open-source alternatives, though they lack E2EE.
Outside of privacy-focused tools, there are popular mainstream options such as Any.do, Google Tasks, Microsoft To Do, Things, TickTick, and Todoist. However, these are not considered privacy-friendly for various reasons.
Discussion
The intention of this proposal is not to endorse specific tools but to initiate a discussion on whether we should add a category for task management tool recommendations. If we decide to proceed, we need to determine what criteria should be established based on the options currently available. I have certainly not listed all available tools, rather just a selection of tools I know.
