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. Features: Visual bubble organization — bubbles hold notes and other bubbles, as deep as you like One note can live in several bubbles at once, no duplicates Drag and drop to rearrange, with pages that grow as you do Confidence tags: Certain, Think About More, Not Sure, Could Be Wrong — or make your own Link notes with typed connections and jump between them Lock private bubbles behind a password Search, sort, filter, and pin Import existing notes from text or by pasting Dark and light mode Free to use. Start as a guest with everything stored on your device, or sign in to sync across devices.
