# Physica vs Physics Zen

The clearest difference is ads: Physics Zen 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 Physics Zen sells 6 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.
