Redesigned for iPad: Home, Records, Profile and Settings no longer stretch on a big screen, and landscape looks the same as portrait.

Local games have a new Game Info sheet: players, board, komi, handicap, rules and times at a glance.
1.5.34 Oct 13
The interface now follows the iOS 26 design: sheets and bottom toolbars use system materials, and the tab bar minimizes when you scroll.
The palette now uses standard system colors, so light and dark mode look more consistent.

A brand-new local AI experience (Challenge AI): the on-device engine is over 8x faster, with adjustable strength, komi and move speed — and you can save and review the game when you finish.
New Kifu Notes: import SGF records, browse them in the list and review them.
iPad portrait refinements: board, player info, game clock and bottom toolbar now scale consistently.
Watch & review: clearer info bar under the board, "back to live" no longer reloads the whole page, smoother progress dragging.
Redesigned profile page; fixed the reversed leading/trailing territory indicator and repeated countdown voice.
