# Kinder vs 图片标注

The clearest difference is in-app purchases: Kinder at none against 图片标注's 1. 图片标注's advantage is iOS requirement (16.0 vs 18.6). On price, ads and device support there is nothing between them.

Both are free to download. 图片标注 sells 1 one-off in-app purchase. Kinder asks for nothing beyond the download.
