ReceptionRating · Positive reviews · Number of ratings

Sleep Tracker holds the better App Store score, 4.9 against 3.7. That said, the two scores are not equally well evidenced: Sleep Tracker has 146 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 67% of Pure Ninja's written reviews are positive against 0% of Sleep Tracker's, so the app with the better star average is not the one people write more warmly about.
