## chessO Description
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
* Streak and accuracy stats – watch blind spots disappear

WHY IT WORKS
Active recall + spaced repetition = durable memory. Medical students use it for anatomy; titled players use it for endgames. chessO brings both into a game-speed interface.
