# CatAI vs 隐藏壁纸

The clearest difference is in-app purchases: CatAI at none against 隐藏壁纸's 1. CatAI also leads on iOS requirement (11.0 vs 15.0). 隐藏壁纸's advantage is device support. On price there is nothing between them.

Both are free to download. 隐藏壁纸 sells 1 one-off in-app purchase. CatAI asks for nothing beyond the download.
