# 上海交通卡官方版 vs KeyFree

The clearest difference is rating: KeyFree at 3.0 against 上海交通卡官方版's 1.9. KeyFree also leads on ads (none vs shown). 上海交通卡官方版's advantage is ratings volume (62 vs 2) and review sentiment (14% vs 0%). On price, in-app purchases, device support and iOS requirement there is nothing between them.

KeyFree holds the better App Store score, 3.0 against 1.9. That said, the two scores are not equally well evidenced: 上海交通卡官方版 has 62 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 14% of 上海交通卡官方版's written reviews are positive against 0% of KeyFree's, so the app with the better star average is not the one people write more warmly about.
