Kifu Reader （棋譜リーダー）
Replay, read and analyse shogi games.
A shogi game viewer for the latest professional games and your own. Candidate-move analysis, a full-game evaluation graph and mate search are all powered by a shogi engine running on your device.
♟ The Suisho5 evaluation function is a free download. Positions are never sent to a server for analysis.
The app’s interface is in Japanese.
Open a game
Latest games
Browse the latest professional shogi games and replay any of them on the board right away, with player names, event and date.
Import your own games
Supports KIF, KI2 and CSA. Paste from the clipboard, pick a file from the Files app, or use “Open in” from another app’s share sheet. Game records exported from Shogi Wars’ analysis screen can be imported too.
Set up any position
Place pieces anywhere on the board, including pieces in hand, then play on from there and start analysing.
Analyse with AI
Position analysis
See up to five candidate moves for the current position, each with an evaluation and its principal variation. The engine keeps thinking while the position is open, so the longer you wait, the deeper it reads.
Full-game analysis and graph
Analyse every position in a game and see the balance of the game as a line graph. Choose 0.5 to 3 seconds per move. While it runs, the move actually played and the engine’s best move are shown side by side, and big swings are listed so you can jump to them.
Mate search
Check whether the current position has a forced mate by consecutive checks, and replay the mating sequence move by move. You set the time limit.
Study mode
Tap a candidate move to play it and explore lines that differ from the game. Analysis continues in every branch.
Suisho5 — free
Download the Suisho5 evaluation function (about 23 MB) for free to make analysis much faster and stronger. All analysis runs on your device; positions are never sent to a server.
Results are kept
Full-game results are saved per game, so reopening a game shows its graph instantly. If you stop part-way, you can resume where you left off.
Keep and carry
Saved games and history
Save games and find the ones you opened again in your history. Imported games stay in their own list.
Saved positions
Name and save any position you want to come back to, then load it from the board editor to continue studying.
Apple Watch
Replay games synced from your iPhone move by move on Apple Watch.
Dark mode
The board and the whole interface follow your device’s light or dark appearance.
Pricing
- Free. Viewing, importing, position analysis, full-game analysis and mate search are all included.

Android

Game files can be opened from your file manager or another app’s share menu. There is no counterpart to the Apple Watch app. The app is free and shows a banner ad on the board screen.
