# 计算器Z vs 公众号伴侣

The clearest difference is in-app purchases: 公众号伴侣 at none against 计算器Z's 1. 计算器Z's advantage is ads (none vs shown). On price, device support and iOS requirement there is nothing between them.

Both are free to download. 计算器Z sells 1 one-off in-app purchase. 公众号伴侣 asks for nothing beyond the download.
