Shogi Vault is a shogi (Japanese chess) study app for reviewing your games and building opening research with an on-device AI engine.

Good moves, dubious moves and blunders are marked automatically on the move tree and the evaluation graph. - Fully on-device AI The YaneuraOu engine with the Suisho5 evaluation runs on your device.

Pro users can switch to stronger evaluation functions. - Variation tree Record unlimited variations from any position, compare them, add comments and pick up your research where you left off. - Import and export Supports KIF, KI2, CSA and SFEN, including games with variations. Imported games are sorted into folders by opening automatically. - Tsume shogi and endgame study Analyze tsume and hisshi problems with the on-device engine. - Optional account sync Sign in with Apple or email to sync settings, research and games across devices.
