# AP Chemistry Practice Exam vs Violearn

The clearest difference is ads: AP Chemistry Practice Exam at none against Violearn's shown. AP Chemistry Practice Exam also leads on iOS requirement (13.0 vs 17.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. AP Chemistry Practice Exam sells 1 one-off in-app purchase and Violearn sells 2 in-app purchases, starting at $12.99 per month. Whichever you choose, the download price is not the number that matters.
