Inside the app

Learn move by move

Every move, explained

Lessons with arrows on the board and the idea behind each move, with white and with black.

A study route for your level

You choose your openings and the app builds the order: first the ones you'll face most at your level.

Your complete repertoire

Italian, London, Sicilian, Caro-Kann, French, Slav and many more, with answers for whatever your opponent plays.

Today's review
What now?: the plans after finishing a line

Practice until it becomes automatic

You make your moves and the opponent answers on its own. Spaced repetition brings back each position right before you forget it, lightning mode puts you against the clock, and when you finish a line, "What now?" teaches you the plans, the pawn structure and the key pieces. And to sharpen your eye, 600 mate-in-1, 2 and 3 problems.
