Chess Openings - ChessAtlas

Train openings, fix mistakes

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Connect Lichess or Chess.com and ChessAtlas shows exactly where you left your opening prep, then drills it back with spaced repetition. Build an opening repertoire you actually remember, and stop losing games to lines you thought you knew. ChessAtlas turns your openings into a simple training routine: learn each line, review it on a spaced-repetition schedule, and connect your real games to catch the exact moves where you went off-book. HOW IT WORKS - Build your own repertoire, paste a PGN, or fork a ready-made opening from the library. - Learn each line move by move, with plain-language notes on the ideas behind the moves. - Link your Lichess or Chess.com account. ChessAtlas checks every game against your prep and flags the first move where you deviated. - Drill those mistakes until they stick, with spaced repetition that brings each line back right before you would forget it. WHAT YOU GET - Your real games, checked against your repertoire, with the first deviation pinpointed. - Spaced-repetition review so lines stay in long-term memory. - Full game analysis with move-by-move accuracy and the quality of every move. - A library of curated openings you can fork and make your own. - Read mode that explains the idea behind each move, not just the notation. - Streaks, levels and a leaderboard to keep the habit going. - Multiple board themes. WHO IT IS FOR Club and improving players who want a repertoire they can trust under pressure, whether you are building your first opening or sharpening lines you already play. Free to start. Upgrade to Premium for unlimited training. Questions or feedback: https://chessatlas.net Terms of Use: https://chessatlas.net/terms Privacy Policy: https://chessatlas.net/privacy
