Mindful Chess is a complete chess training app: solve puzzles, learn openings that stay with you, analyze any position and play a bot, all on your device. Solving quickly earns bonus points, but every wrong move costs points too, so the game rewards careful calculation over guessing.
100% OFFLINE — POWERED BY MINDFUL ENGINE
Every feature runs on your device: the puzzles, the opening lessons, the analysis board and the bot itself. Mindful Engine is a chess engine written from scratch for this app, so there is no third-party server anywhere in the loop. Put your phone in airplane mode and the whole app keeps working.
FEATURES
• 1.4 Million Offline Puzzles: Tactics taken from real games, ready anytime with no connection needed. A progress bar shows how many moves each puzzle needs, and the move list shows what has been played.
• NEW! See Why a Move Fails: Play a wrong move and your opponent's best answer appears on the board with a one-line explanation, such as "Check, but not mate: Black blocks with ...f6."
• Daily Puzzle — Free for Everyone: One hard puzzle a day, the same for every player in the world, with a single attempt. The clock starts the moment the board is revealed and the fastest solve tops the leaderboard; each mistake adds 20 seconds. Build a streak, share your result and, if you like, get a reminder at the time you choose.
• Opening Trainer — Openings That Actually Stick: Every line is first walked through with move-by-move explanations, then you play it back yourself. Spaced repetition remembers exactly which move you struggle with and brings it back just before you would forget it. 89 variations across 26 major openings, from the Sicilian and the London System to the Catalan and the Benko Gambit, trainable from either side. Starter lines in the Italian Game and the French Defence are free; the full course unlocks with Pro.
• NEW! Analyze Position, Now From a Screenshot (Pro): Set the pieces up yourself, or pick a screenshot of a board and the position is rebuilt on your device; any square it isn't sure about is marked for you to check. See the best move and a full evaluation, play any legal move to get the engine's reply, then continue the position against the bot. Made for finished games, puzzles and study positions.
• NEW! Opening Encyclopedia, Rebuilt (Pro): Over 3,800 named openings and variations from the open Lichess opening database, arranged in five ECO volumes and searchable by name or code.
• Three Bot Difficulties — Free: Beginner, Club and Master, all on your device. The bot opens from a real opening book and only starts making mistakes once the opening is over, because that is when real players start making them.
• Hints and Blunder Coach (Pro): Ask for the best move in the middle of a game against the bot, catch a blunder the moment you play it and take it back. In puzzles, see the next move when you're stuck.
• Live Match — Face-to-Face Multiplayer: Challenge a friend in the same room. Two devices connect directly over your local network, no internet required. Choose your color and time control (3, 5 or 10 minutes, or untimed), offer draws and play instant rematches.
• A Real Wooden Board: Maple and walnut squares, pieces that glide, legal moves that light up, and crisp sounds and haptics on every move.
• Game Center: Two leaderboards, your all-time score and the daily race (requires internet to sync).
