# Phys 1 vs Active and Passive Transport

The clearest difference is iOS requirement: Phys 1 at 9.0 against Active and Passive Transport's 12.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
