# Fraction Challenge vs Sem

The clearest difference is ads: Fraction Challenge at none against Sem's shown. Fraction Challenge also leads on iOS requirement (13.0 vs 16.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Fraction Challenge sells 1 one-off in-app purchase and Sem sells 9 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.
