Chess Virtuoso is the smartest way to learn and memorize chess openings.

The app scores your performance and schedules each line for review at exactly the right moment — using the SM-2 algorithm, the same method trusted by top memory tools. Study less, remember more. ◆ 300+ OPENINGS Explore a curated library of official openings from the classics to modern systems: Ruy Lopez, Sicilian Defense, Queen's Gambit, King's Indian, Caro-Kann, French Defense, London System, and hundreds more. Every opening includes all major variants with full theory coverage. ◆ DEEP VARIANT TRAINING Drill every branch of an opening, move by move. See your mastery rate per variant, identify the lines you keep forgetting, and focus your practice where it matters most. ◆ BUILD YOUR OWN REPERTOIRE Import any PGN file from your games or study materials. Or build an opening directly on the board — add new variants, edit existing lines, and create a fully custom repertoire tailored to your style. ◆ DAILY TRAINING GOALS Set a daily review target and let Chess Virtuoso schedule your sessions automatically. Track your streak, earn XP, and unlock achievements as you progress. ◆ PROGRESS TRACKING Watch your mastery grow with detailed stats: success rate, total reviews, overdue lines, and an activity heatmap showing your training history. ◆ AVAILABLE IN ENGLISH & FRENCH Chess Virtuoso is free to download and use.
