I am searching for an App (ideally for both Mac OS X and iOS), which combines a decent ToDo list and task manager with something like Apples notes application.
To add more background: I want to use it to keep track of scientific projects or projects in general, where the main focus is not to keep track the time frame (like a project management software does) but to document process and help organizing necessary next steps (and be able to check them off), adding meeting notes, tagging for better search, clear structuring (folders etc). It would be perfect if the Apple Pencil is supported so that I can add ideas and meeting notes directly by hand. Of course, I also want to add tables, format text, add files and figures etc.
Is there anything out there recommandable?
