# SonicTonic vs Mesmerize

The clearest difference is monetization model: SonicTonic at free with in-app purchases against Mesmerize's subscription. SonicTonic also leads on review sentiment (71% vs 34%) and iOS requirement (14.0 vs 18.0). Mesmerize's advantage is ratings volume (57K vs 11). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. SonicTonic sells 13 in-app purchases, starting at $2.99 per month and Mesmerize sells 11 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Mesmerize holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Mesmerize has 57K ratings behind it against 11, so its average is the more settled of the two. Written reviews complicate that: 71% of SonicTonic's written reviews are positive against 34% of Mesmerize's, so the app with the better star average is not the one people write more warmly about.

SonicTonic ships an update every 2 weeks, Mesmerize every 3 weeks. The most recent releases landed on October 24, 2026 and November 1, 2026 respectively.
