I’ve been looking into all sorts of them recently: logseq, appflowy, vikunja, etc. What tools do you use? Why? What problems did you run into with the previous set of tools you used for this job?
Right now I’m primarily interested in finding a “zero-knowledge” (cloud provider doesn’t have access to my data) system for task management. Needs to be able to have recurring tasks and tasks organized in some interesting/useful ways (by projects/labels/something, maybe a kanban and table view). Deadlines and time tracking/planning interesting but not required.
I use the app opentask. Based on your criteria, it’s exactly what you’re looking for. It’s all stored locally on your phone, it has the ability to set recurring tasks, and you can create categories of preset and custom tasks. Deadlines can be set as far into the future as you need, down to the minute. It’s available on F-Droid.
