# Sound Machine 3D vs Hypnosis

The clearest difference is rating: Sound Machine 3D at 4.6 against Hypnosis's 3.7. Sound Machine 3D also leads on ratings volume (70 vs 7). Hypnosis's advantage is review sentiment (100% vs 82%). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Sound Machine 3D sells 1 in-app purchase, starting at $5.99 per year and Hypnosis sells 16 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Sound Machine 3D holds the better App Store score, 4.6 against 3.7. That said, the two scores are not equally well evidenced: Sound Machine 3D has 70 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 82% of Sound Machine 3D's written reviews are positive against 100% of Hypnosis's, so the app with the better star average is not the one people write more warmly about.

Sound Machine 3D ships an update every 5 weeks, Hypnosis every 3 weeks. Both last shipped on October 24, 2026.
