ChessAtlas helps you build a chess opening repertoire and actually retain it. Import your games from Lichess or Chess.com, spot where you deviated from your prep, and train every line with spaced repetition so it sticks. Browse the course library or build your own from scratch. Stop re-learning the same openings — drill them once, remember them forever.
DarkSquares helps you master blindfold chess through a progressive training system. Start with fundamentals like square colors and coordinates, then advance to knight paths, tactical puzzles, and replaying famous games (Morphy, Kasparov, Carlsen) entirely in your head.
The app gradually removes visual cues — from full board to silhouettes to complete blindfold. Play against AI at multiple difficulty levels without ever seeing the pieces.
Available on web, iOS, and Android.
