# Gravity
> A minimal notes app with one stream: append, review, and rescue what still matters.
Gravity is a notes app built on Andrej Karpathy's append-and-review method. You write everything into one stream, new notes go on top, older notes sink, and you swipe to bring back anything that still matters. There are no folders or accounts; a tag is just a word and a colon at the start of a note.
