# SleepStream 2 vs Pzizz

The clearest difference is rating: Pzizz at 4.8 against SleepStream 2's 3.8. Pzizz also leads on ratings volume (9.7K vs 33). SleepStream 2's advantage is review sentiment (81% vs 72%) and iOS requirement (8.0 vs 16.0). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. SleepStream 2 sells 10 one-off in-app purchases and Pzizz sells 11 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

Pzizz holds the better App Store score, 4.8 against 3.8. That said, the two scores are not equally well evidenced: Pzizz has 9.7K ratings behind it against 33, so its average is the more settled of the two. Written reviews complicate that: 81% of SleepStream 2's written reviews are positive against 72% of Pzizz's, so the app with the better star average is not the one people write more warmly about.

SleepStream 2 ships an update every 2 months, Pzizz every 5 weeks. The most recent releases landed on October 23, 2026 and October 28, 2026 respectively.
