A minimalist note-taking app with a single information flow
Gravity is a minimalist note-taking based on the "Append-Review" note-taking method shared by Andrej Karpathy: all ideas are written in the same information flow, no folders, no labels, no accounts. After a period of time, scroll back, and if there are still useful ones, just swipe up and push them to the top, and the useless ones will sink naturally.
It supports iPhone, iPad, Mac and Android. Notes only exist on this machine. iCloud synchronization is optional between Apple devices. One buyout, no subscription. The latest version also adds an entrance for the AI agent to read and write notes, making it easier to use this stream as the agent's long-term memory.
Note: The developer said that the iPhone and Mac versions are temporarily removed from the App Store due to the developer account renewal process. The Android version can be downloaded normally.
