FujiGoban Free

FujiGoban Free is a free, ad-supported Go kifu player and editor designed for players who want to replay, study and annotate Go games on a mobile device. The app opens common record formats, lets you step through moves, add comments and variations, and save or share finished SGF files, making it useful for reviewing matches, studying joseki, or preparing post-game notes with training partners. As the free version of the Pro release, FujiGoban Free keeps the core review and editing features while adding in-app ads, offering a convenient way to browse and manage game records on the go.

Key Features

⭐ Open and replay SGF, NGF, UGF and GIB game record files with move-by-move navigation.

⭐ Paste SGF data from the clipboard, record new games and edit existing kifu with comments and variations.

⭐ Human vs human board play for score review and face-to-face analysis (no computer opponent).

⭐ Undo and redo edits (around 30 steps) and add move numbers, markups and game information.

⭐ Send the current board position to the built-in analysis engine (Fujigoban.js) and capture screenshots for study.

⭐ Backup, restore and share SGF records as text or files; open attachments from email or from cloud storage.

Advantages

✅ Designed for players: FujiGoban Free focuses on game review and annotation rather than playing against an engine.

✅ Supports multiple record formats so you can work with files from different sources without conversion.

✅ Lightweight editing tools let you add comments, variations and markups to build study materials or teaching examples.

✅ File backup and sharing make it easy to exchange kifu with teammates or preserve your game library.

Disadvantages

❎ The free edition is ad-supported, so expect occasional advertisements compared with the Pro release.

❎ There is no human vs CPU mode; the app is intended for replay and human-to-human review only.

❎ Undo/redo history is limited to about 30 steps, which may be restrictive during deep editing sessions.
