# Physica vs Quant Math

The clearest difference is in-app purchases: Quant Math at none against Physica's 6. Quant Math also leads on ads (none vs shown) and iOS requirement (15.1 vs 17.6). On price and device support there is nothing between them.

Both are free to download. Physica sells 6 in-app purchases, starting at $6.99 per month. Quant Math asks for nothing beyond the download.
