# 快递100 vs 《单位换算器》

That said, the two scores are not equally well evidenced: 快递100 has 1.4K ratings behind it against 9, so its average is the more settled of the two. Written reviews complicate that: 74% of 快递100's written reviews are positive against 100% of 《单位换算器》's, so the app with the better star average is not the one people write more warmly about.
