About
Memory, not luck.
chessO turns any spare minute into a laser-focused pattern workout. Set how many pieces you want to memorise and how long you want to glimpse the board. The app then auto-generates a fresh position and challenges you to rebuild it square-perfect.
CORE FEATURES
* Instant board generator – zero prep, unlimited variety
* Custom preview timer – pick 1-10 seconds for short- or long-term recall
* Pattern Lock drills – place pieces; instant feedback shows mistakes
