# MathBoard vs 口算成长

The clearest difference is iOS requirement: 口算成长 at 13.0 against MathBoard's 15.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. MathBoard sells 3 in-app purchases, starting at $2.99 per month and 口算成长 sells 4 in-app purchases, starting at $0.99 per 7 days. Whichever you choose, the download price is not the number that matters.
