# Green P vs Ontario 511

Ontario 511 holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Green P has 275 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 16% of Green P's written reviews are positive against 9% of Ontario 511's, so the app with the better star average is not the one people write more warmly about.
