# Lief App vs Somnee

The clearest difference is rating: Lief App at 4.0 against Somnee's 3.7. Lief App also leads on iOS requirement (13.0 vs 15.1). Somnee's advantage is review sentiment (64% vs 45%) and ratings volume (71 vs 2). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Lief App holds the better App Store score, 4.0 against 3.7. That said, the two scores are not equally well evidenced: Somnee has 71 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 45% of Lief App's written reviews are positive against 64% of Somnee's, so the app with the better star average is not the one people write more warmly about.

Lief App ships an update every 5 weeks, Somnee every 2 months. The most recent releases landed on October 3, 2026 and October 7, 2026 respectively.
