# Nonogram vs PixelFlow

The clearest difference is in-app purchases: Nonogram at none against PixelFlow's 4. Nonogram also leads on ratings volume (648 vs 1) and iOS requirement (13.0 vs 17.0). PixelFlow's advantage is ads (none vs shown) and update cadence (every 9 days vs every 4 months). On price, monetization model and device support there is nothing between them.

Both are free to download. PixelFlow sells 4 in-app purchases, starting at $1.99 per 7 days. Nonogram asks for nothing beyond the download.

PixelFlow holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Nonogram has 648 ratings behind it against 1, so its average is the more settled of the two.

Nonogram ships an update every 4 months, PixelFlow every 9 days. The most recent releases landed on October 20, 2026 and October 5, 2026 respectively.
