ReceptionRating · Positive reviews · Number of ratings

OOLER holds the better App Store score, 4.8 against 4.2. That said, the two scores are not equally well evidenced: OOLER has 3.2K ratings behind it against 335, so its average is the more settled of the two. Written reviews complicate that: 40% of OOLER's written reviews are positive against 67% of Sleep Easy's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

OOLER ships an update every 4 weeks, Sleep Easy every 5 weeks. The most recent releases landed on October 24, 2026 and October 25, 2026 respectively.
