Verdict

The call

The clearest difference is rating: SleepScore Max at 4.6 against Mind Window's 4.0. SleepScore Max also leads on ratings volume (446 vs 18) and update cadence (every 2 weeks vs every 2 months). Mind Window's advantage is monetization model (free vs free with in-app purchases). On price, review sentiment, ads and in-app purchases there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

SleepScore Max holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: SleepScore Max has 446 ratings behind it against 18, so its average is the more settled of the two. Written reviews complicate that: 42% of SleepScore Max's written reviews are positive against 50% of Mind Window's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

SleepScore Max ships an update every 2 weeks, Mind Window every 2 months. The most recent releases landed on October 26, 2026 and October 24, 2026 respectively.
