Chess Openings Coach - Theoria

Built with a FIDE Master. Learn an opening, practice it without hints, and use your own games to find what to work on next.

Know your next move. Learn chess openings on the board, practice without hints, and build a repertoire you can remember when the game begins.

START WITH ONE OPENING Choose your level and goal, then explore openings for White and Black. From the Queen’s Gambit to the Caro-Kann Defense, learn one line at a time without getting buried in theory.

UNDERSTAND, THEN PRACTICE Study the moves with guidance. Switch to practice to test your memory, revisit mistakes, and follow your progress as the lines become familiar.

MAKE TRAINING A HABIT Fit a few lines into your day. Add chess puzzles to your training and track your progress across your repertoire.

Theoria is built for beginners learning their first opening and club players who want a practical way to rehearse their lines.

Available in English, French, and Russian. Free to download, with optional in-app purchases for premium access.

Choose your first opening and start learning.
