I’ve always used joplin mobile for notes and vikunja for tasks and reminders. Vikunja has projects and labels for organizing tasks, and supports list, table, kanban, and a timeline view. There’s a paid version (for corporations, I think) at https://vikunja.io/, but there are loads of other free to use instances. I personally use https://todo.projectsegfau.lt/. Edit: I wholeheartedly hope you at least try vikunja https://try.vikunja.io/, because it’s one of my most used and beloved services.
