Verdict

The call

The clearest difference is review sentiment: Deep Sleep, Insomnia Help at 77% against OOLER's 40%. OOLER's advantage is in-app purchases (none vs 20) and update cadence (every 4 weeks vs every 11 months). On price, ads and device support there is nothing between them.

Both are free to download. Deep Sleep, Insomnia Help sells 20 one-off in-app purchases. OOLER asks for nothing beyond the download.

ReceptionRating · Positive reviews · Number of ratings

OOLER holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: OOLER has 3.1K ratings behind it against 419, so its average is the more settled of the two. Written reviews complicate that: 77% of Deep Sleep, Insomnia Help's written reviews are positive against 40% of OOLER's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Deep Sleep, Insomnia Help ships an update every 11 months, OOLER every 4 weeks. Both last shipped on October 8, 2026.
