# Sonography ARDMS Prep vs Physics Handbook

The clearest difference is iOS requirement: Sonography ARDMS Prep at 13.0 against Physics Handbook's 15.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Sonography ARDMS Prep sells 4 in-app purchases, starting at $6.99 per 7 days and Physics Handbook sells 3 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.
