Smart review
Spaced repetition brings back each move just before you would forget it, so review time goes where it matters.
Chess opening trainer for iPhone
Learn the chess openings you will actually face, a few minutes a day. Hops, your knight coach, explains every move in plain words, then you play the line against Rook Bot until it is yours.
For iPhone. No account needed.
Understand, do not memorize
A move you understand is a move you remember. Every move in every course comes with a short headline and one or two plain sentences: what it does, and what to watch for next.

Practice that sticks
Rook Bot plays the replies club players really meet. You play the moves you just learned. Every unit ends with a match, so the line moves from the lesson into your hands.

How it works
Pick an opening and your level. The path shows every unit ahead, and each unit takes a few minutes.
Hops walks you through the new moves, one reason at a time.
Play the moves yourself. Hops steps in only when you need a hint.
Each unit hides one trap: learn to set it, and learn to punish it.
Play the whole line in a match. Win it and the next unit opens.
The repertoire
A complete repertoire for both colors, from first moves to the plans that follow. Lines are chosen from about 2.5 million blitz and rapid games between players rated 1000 to 1999.
Win more games
Some games are over by move ten. Learn the classic tricks and the real mistakes club players keep making, then learn how to punish them when someone tries one on you.

Stay on track

Who it is for
You know how the pieces move, but the first ten moves feel like guesswork. Start with one opening for White and one for Black.
You play blitz and rapid and keep losing early. Learn the lines you actually meet at your rating, not engine lines from top events.
You want a repertoire you understand. Build it course by course and keep it fresh with a few minutes of review.

From real games. The lines and reply statistics come from about 2.5 million blitz and rapid games between players rated 1000 to 1999 in the Lichess open database (CC0). Our moves were checked with a chess engine, so you learn what club players actually play, without the bad habits.
Every move has a short explanation of its purpose, so you learn the plan behind the opening. When your opponent leaves the book, you still know what you were trying to do.
Your practice opponent. Rook Bot answers with the moves club players really choose in that opening, so a match feels like the games you play online.
No. There is no sign up and no login. All lessons, positions and traps ship inside the app, so you can practice offline, on a train or on a plane.
The app uses spaced repetition. Moves you know well come back less often, and moves that keep slipping come back sooner. About five minutes a day keeps a whole repertoire fresh.
