# Nonograms Katana vs Hashi Solver

The clearest difference is rating: Nonograms Katana at 4.8 against Hashi Solver's 4.0. Nonograms Katana also leads on ratings volume (6.8K vs 1). Hashi Solver's advantage is review sentiment (100% vs 83%). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Nonograms Katana sells 3 one-off in-app purchases and Hashi Solver sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Nonograms Katana holds the better App Store score, 4.8 against 4.0. That said, the two scores are not equally well evidenced: Nonograms Katana has 6.8K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 83% of Nonograms Katana's written reviews are positive against 100% of Hashi Solver's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 3 months. Both last shipped on October 24, 2026.
