# Piczle Lines vs Nonograms Katana

The clearest difference is update cadence: Piczle Lines at fortnightly against Nonograms Katana's every 4 months. Piczle Lines also leads on review sentiment (91% vs 83%) and iOS requirement (8.0 vs 15.0). Nonograms Katana's advantage is ratings volume (6.8K vs 16) and rating (4.8 vs 4.6). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Piczle Lines sells 6 one-off in-app purchases and Nonograms Katana sells 8 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 4.6. That said, the two scores are not equally well evidenced: Nonograms Katana has 6.8K ratings behind it against 16, so its average is the more settled of the two. Written reviews complicate that: 91% of Piczle Lines's written reviews are positive against 83% of Nonograms Katana's, so the app with the better star average is not the one people write more warmly about.

Piczle Lines ships an update fortnightly, Nonograms Katana every 4 months. The most recent releases landed on November 1, 2026 and November 11, 2026 respectively.
