# T檢定 vs Whiteboardy

The clearest difference is device support: T檢定 at 4 against Whiteboardy's 1. T檢定 also leads on iOS requirement (15.0 vs 18.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. T檢定 sells 1 one-off in-app purchase and Whiteboardy sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
