Verdict

The call

The clearest difference is review sentiment: Frequency Generator (Sound) at 50% against Spectrum Analyzer's 5%. Frequency Generator (Sound) also leads on iOS requirement (13.0 vs 16.0). Spectrum Analyzer's advantage is rating (4.2 vs 3.2) and update cadence (fortnightly vs every 3 months). On price, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Spectrum Analyzer holds the better App Store score, 4.2 against 3.2. That said, the two scores are not equally well evidenced: Spectrum Analyzer has 198 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 5% of Spectrum Analyzer'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

Spectrum Analyzer ships an update fortnightly, Frequency Generator (Sound) every 3 months. The most recent releases landed on October 16, 2026 and October 10, 2026 respectively.
