# Flash Math vs 1×1 Master

The clearest difference is device support: Flash Math at 3 against 1×1 Master's 1. Flash Math also leads on iOS requirement (13.0 vs 18.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. Flash Math sells 2 one-off in-app purchases and 1×1 Master sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
