About this app

Learn chess openings the easy way — no walls of text, just clear guidance, puzzles, and practice that sticks.

Whether you’re brand new to chess or already know the basics, mastering chess openings is the fastest way to improve your play. Instead of drowning in endless theory, our app makes learning openings simple, practical, and fun — built for players rated from 300 to 1500+ who want to learn chess efficiently.

Why learn chess openings with us?

1. Pick your opening
Explore a growing library of 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.

2. Study Mode
No more reading heavy books. Each move comes with a short, clear explanation. You’ll always understand not just what the best move is, but why it works. It’s like having a coach in your pocket, guiding you step by step.

3. Practice Mode
Test your knowledge without hints. Moves appear randomly so you can’t just rely on rote order. Helpful arrows on the first move show your options, so you’re never completely lost — perfect for beginners still learning the basics.

4. Muscle Memory Training
Chess is about pattern recognition. Our training repeats short, digestible lines until you build real muscle memory. Soon, you’ll play your moves automatically in games on Chess.com or Lichess, just like you practiced.

5. Tactics and puzzles
Openings lead directly into middlegame tactics. That’s why we include puzzle-like drills designed to sharpen your calculation and help you spot traps, forks, and pins early. Solving chess puzzles in context makes studying openings even more powerful.

6. Learn in your language
Full support for English, Russian, and French. More languages are planned so that players around the world can study and practice comfortably.

Who is this app for?

- Beginners who want to learn chess openings without getting overwhelmed.
- Casual players who know the rules but want to bring structure to their study.
- Club players looking for a faster way to improve their repertoire and practice lines.

Why it works

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. You’ll walk into your next game confident, prepared, and ready to surprise your opponent in the opening.

Upcoming features
We’re just getting started. Our roadmap includes:

- Smarter practice that adapts to your mistakes.
- Progress tracking: see how many lines you’ve mastered.
- More puzzles tied to your chosen repertoire.
- Additional openings based on community requests.
