ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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.
