# 扫描仪 vs 超级写作

The clearest difference is device support: 扫描仪 at 2 against 超级写作's —. 扫描仪 also leads on iOS requirement (10.0 vs 12.0). On price and in-app purchases there is nothing between them.

Both are free to download. 扫描仪 sells 4 in-app purchases, starting at $4.49 per 7 days and 超级写作 sells 7 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.
