# SAT Study Guide vs Mental Math

The clearest difference is iOS requirement: SAT Study Guide at 15 against Mental Math's 17.6. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. SAT Study Guide sells 1 one-off in-app purchase and Mental Math sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
