About this app

ALL IN ONE OPENINGS CHESS TEACHER & TRAINER

Imagine having a master chess instructor for openings in your pocket 24/7. Theoria is a chess training app to perfect chess openings and lines like a pro while growing your chess opening repertoire.

VAST LIBRARY OF CHESS OPENINGS

♞Discover great variety of chess openings. From classics like the Queen’s Gambit and Caro-Kann Defense to gambits and sidelines. New openings and lines are added regularly, so you always have fresh material to study.

♜ Select your goal and rating, and get a suggested chess opening to start. Then instantly practice on the chess board, and learn as you go. Forget about the long text chess guides and techniques. Each chess move is described in the top part, if you want to do in-depth chess analysis as you practice.

PRACTISE, REVISE & MASTER

♛ Most chess apps focus only on puzzles or tactics. Others drown you in text or video lectures. This app combines the best of both worlds: study + practice.

You first understand the moves, then drill them repeatedly until they become part of your long-term memory. Try the revise mode to see and learn from your mistakes and master each opening.
