# Sonic Hz Frequency Generator vs Frequency Generator (Sound)

The clearest difference is rating: Sonic Hz Frequency Generator at 4.2 against Frequency Generator (Sound)'s 3.0. Sonic Hz Frequency Generator also leads on ratings volume (107 vs 4). Frequency Generator (Sound)'s advantage is review sentiment (50% vs 10%) and iOS requirement (13.0 vs 16.6). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Sonic Hz Frequency Generator sells 4 in-app purchases, starting at $6.99 per 7 days and Frequency Generator (Sound) sells 1 in-app purchase, starting at $0.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Sonic Hz Frequency Generator holds the better App Store score, 4.2 against 3.0. That said, the two scores are not equally well evidenced: Sonic Hz Frequency Generator has 107 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 10% of Sonic Hz Frequency Generator's written reviews are positive against 50% of Frequency Generator (Sound)'s, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 3 months. The most recent releases landed on September 22, 2026 and September 16, 2026 respectively.
