Your openings, drawn as lines — and told plainly what has decayed.
Gambora keeps the openings you actually play as a map you can read at a glance, names every position it recognises from 3,810 openings, drills what is due on a schedule, and shows the exact move where a game you played left your own book. Lines are built by playing moves on the board, never by typing notation. Everything stays on your device: no account, no cloud, no tracking.
