# 尺子测量 vs 驾照练习册

The clearest difference is iOS requirement: 尺子测量 at 11.0 against 驾照练习册's 13.0. On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. 尺子测量 sells 5 in-app purchases, starting at $1.99 per 7 days and 驾照练习册 sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
