# Prisma vs Questroom

The clearest difference is ads: Questroom at none against Prisma's shown. Prisma's advantage is iOS requirement (15.1 vs 18). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Prisma sells 1 in-app purchase, starting at $14.99 per year and Questroom sells 3 in-app purchases, starting at $5.99 per 3 months. Whichever you choose, the download price is not the number that matters.
