Chess Engine

Sep 9, 2026

Stockfish 19 is here - up to +44 Elo stronger, and its neural network now downloads after install, so the app itself is a much smaller download.

Also in this release:
• Board scanner (Alpha): finds the board's corners and straightens the photo
• Redesigned bottom sheets
• Opening Explorer and Tablebase now have their own screens
• Chess960, Play and Analysis rebuilt on the new design
• Fixes to clocks, daily challenge, streaks and rewarded hints
