What’s new

Version 5.0.5 · Updated October 5, 2026

Your Board Keeps Up With You Fixed a bug on iOS 27 where a number you placed didn't appear on the board until you tapped another cell. Long-press notes are fixed too — holding a number to note it everywhere it fits sometimes stopped working partway through, usually from around 5 onward. Every digit and note now shows up the moment you enter it, on both the full board and the zoomed-in view. Thanks for reporting this — happy solving!
