# Zen Flip Clock vs Simple Clock

That said, the two scores are not equally well evidenced: Zen Flip Clock has 6.2K ratings behind it against 297, so its average is the more settled of the two. Written reviews complicate that: 72% of Zen Flip Clock's written reviews are positive against 75% of Simple Clock's, so the app with the better star average is not the one people write more warmly about.
