Shogi Analysis Downloads & RevenueShogi Analysis · App Store

Review your shogi games with a real engine, right on your phone.
Paste a KIF from Shogi Wars, Shogi Quest or anywhere else and get win-rate graphs, best moves and lines, move by move as the analysis arrives.

■ NO WAITING
• Positions are analyzed in parallel and results appear move by move, so you can start right away. A full game takes about 10 seconds (~100 moves; varies with length and connection)

■ MISSED MATES BECOME TSUME PUZZLES
• Mates of up to 7 moves you missed become puzzles you play out to checkmate against the toughest defense
• Missed mates of 9+ moves and blunders become next-move problems

■ "WHAT IF…?" TRY A MOVE
• Move a piece on the analysis board to see its win rate and the top 3 replies, then keep playing out the line

■ PLAY THE ENGINE FROM ANY POSITION
• Tap "Play from here" in Analysis to take your side and play the game out against the engine. Pick the opponent's strength by rank; while you follow the actual game, it replies with the actual moves
• Win rate and evaluation stay visible as you play. Stuck? "Show best move" reveals the answer, and you can undo
• Finished games are saved and analyzed like any other. Checks and mates appear in brush lettering, with a sound and a light tap when a piece lands

■ YOUR OWN PROBLEM SET
• Built only from clear mistakes: a win thrown away, a missed mate, missed material, or a big blunder
• Auto practice serves your newest problems first, with no daily limit, or browse by length or situation
• Answer on the board, with hints, then compare win rates with the best move (e.g. 61% → 38%)
• Mark problems Mastered or Review again. Ones you miss come back after 1, 3, 8 and 30 days

■ GAME ANALYSIS
• Win-rate graph, top 3 candidates with win rates, and the best move as an arrow with a replayable line
• The best move's aim in words ("Aims to check and win the rook") and mate lengths ("Mate in 7")
• Key points flag forks, skewers, discovered checks, threatmates and more
• A mark (◎ ○ △ ×) shows whether the last move matched the best move
• Game list with mini win-rate graphs, blunder markers and openings, filterable by opening
• Western (P-76) or Japanese notation, and Light, Dark or system appearance

■ EASY TO START
• Free to start, with no sign-up or email needed (free plan: analyze 3 games, try moves in 3 games and play 3 games a day)
• Paste a game record, pick a file, or import via Share. Add several games at once
• Shogi Wars and Shogi Quest game links import directly. KIF files from Lishogi and 81Dojo work too
• No player names? Just pick Sente or Gote. Mid-game starts work, and a position without moves (diagram or SFEN) can become a mate problem

■ GOOD TO KNOW
• Formats: KIF, KI2 and CSA (plus USI/SFEN and JKF)
• Adding and analyzing games needs a connection; problems can be solved offline
• Delete your account and its data from the Account screen. An optional email lets you restore it on a new phone

■ PREMIUM (AUTO-RENEWING SUBSCRIPTION)
• Unlimited game analysis, what-if moves and
