# 趣质检 vs 仅此一张

The clearest difference is in-app purchases: 趣质检 at none against 仅此一张's 1. 趣质检 also leads on iOS requirement (12.0 vs 17.0). On price, ads and device support there is nothing between them.

Both are free to download. 仅此一张 sells 1 one-off in-app purchase. 趣质检 asks for nothing beyond the download.
