Gravity Notes
Gravity is a notes app built on Andrej Karpathy's append-and-review note. Every note goes into one list with the newest on top, and older notes sink until you swipe one back up. It runs on iPhone, iPad, Android and Mac, syncs between them with Gravity Sync, and connects to Claude and ChatGPT so they can save and search your notes. You pay once, with no subscription. I build it on my own in the Germany.
