# Nanit vs Sleep trainer

The clearest difference is price: Nanit at Free against Sleep trainer's $2.99. Nanit also leads on update cadence (weekly vs every 4 months) and ratings volume (39K vs 11). Sleep trainer's advantage is in-app purchases (none vs 10) and review sentiment (92% vs 66%). On ads and device support there is nothing between them.

Nanit is free to download; Sleep trainer costs $2.99 up front. Nanit sells 4 in-app purchases, starting at $119.99 per year. Sleep trainer asks for nothing beyond the download.

Nanit holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Nanit has 39K ratings behind it against 11, so its average is the more settled of the two. Written reviews complicate that: 66% of Nanit's written reviews are positive against 92% of Sleep trainer's, so the app with the better star average is not the one people write more warmly about.

Nanit ships an update weekly, Sleep trainer every 4 months. The most recent releases landed on November 7, 2026 and November 3, 2026 respectively.
