# Nonograms vs Calcudoku

The clearest difference is ads: Nonograms at none against Calcudoku's shown. Calcudoku's advantage is device support (3 vs 1). On price, in-app purchases and iOS requirement there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
