Nubble organizes your thoughts in visual bubbles. Create notes, nest them inside your bubbles, tag them by how sure you are, and link related ideas — so your notes reflect how you actually think, not just when you wrote them down. Most notes apps ask you to decide on a structure before you have anything to put in it. Nubble lets the pile exist, then makes it something you can see and move around.
