# Piyo Math vs Number Crossword

The clearest difference is in-app purchases: Piyo Math at none against Number Crossword's 4. Piyo Math also leads on ads (none vs shown). Number Crossword's advantage is device support (3 vs 1) and iOS requirement (14.0 vs 16.1). On price there is nothing between them.

Both are free to download. Number Crossword sells 4 one-off in-app purchases. Piyo Math asks for nothing beyond the download.
