# Physica vs ClassFactor

The clearest difference is ads: ClassFactor at none against Physica's shown. On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. Physica sells 6 in-app purchases, starting at $6.99 per month and ClassFactor sells 6 in-app purchases, starting at $20.00 per month. Whichever you choose, the download price is not the number that matters.
