# Frequency Generator vs Frequency Generator (Sound)

The clearest difference is rating: Frequency Generator at 4.4 against Frequency Generator (Sound)'s 3.0. Frequency Generator also leads on ads (none vs shown) and update cadence (every 3 weeks vs every 3 months). Frequency Generator (Sound)'s advantage is review sentiment (50% vs 24%) and device support (3 vs 1). On price, in-app purchases and monetization model there is nothing between them.

Both are free to download. Frequency Generator sells 6 in-app purchases, starting at $9.99 per year 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.

Frequency Generator holds the better App Store score, 4.4 against 3.0. That said, the two scores are not equally well evidenced: Frequency Generator has 83 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 24% of 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.

Frequency Generator ships an update every 3 weeks, Frequency Generator (Sound) every 3 months. The most recent releases landed on November 7, 2026 and November 4, 2026 respectively.
