# 空白相册 vs 图片标注

The clearest difference is iOS requirement: 图片标注 at 16.0 against 空白相册's 18.0. On price and in-app purchases there is nothing between them.

Both are free to download. 空白相册 sells 1 one-off in-app purchase and 图片标注 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
