An iOS and macOS native note-taking app that offers capabilities in structuring and organizing content using bi-directional linking.
Sticky notes on a wall? Random ideas on a whiteboard? Outlining or mind-mapping apps? Kanban cards, notes connected in a Roam Research-style wiki, random ideas scribbled down on paper until something sticks? What are your favorite tools to come up with new ideas, individually or as a team?
Looking for something easy to set up, that looks good, and preferably not VC-backed because I want it to be around for a while.
