Verdict

The call

The clearest difference is review sentiment: Sleep at 60% against Oh my teeth's 14%. Sleep also leads on ratings volume (9.8K vs 1) and iOS requirement (13.0 vs 15.0). Oh my teeth's advantage is rating (5.0 vs 4.3) and in-app purchases (none vs 10). On price, update cadence, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Oh my teeth holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Sleep has 9.8K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 60% of Sleep's written reviews are positive against 14% of Oh my teeth's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Sleep ships an update every 3 weeks, Oh my teeth every 4 weeks. The most recent releases landed on November 9, 2026 and November 3, 2026 respectively.
