# Sound Spectrum Analysis vs Frequency Analyzer

The clearest difference is review sentiment: Sound Spectrum Analysis at 60% against Frequency Analyzer's 0%. Sound Spectrum Analysis also leads on iOS requirement (15.6 vs 17.2). Frequency Analyzer's advantage is rating (4.5 vs 3.6) and update cadence (every 8 days vs every 5 weeks). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Sound Spectrum Analysis sells 1 one-off in-app purchase and Frequency Analyzer sells 11 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Frequency Analyzer holds the better App Store score, 4.5 against 3.6. Both are backed by a comparable volume of ratings — 42 and 166 respectively. Written reviews complicate that: 60% of Sound Spectrum Analysis's written reviews are positive against 0% of Frequency Analyzer's, so the app with the better star average is not the one people write more warmly about.

Sound Spectrum Analysis ships an update every 5 weeks, Frequency Analyzer every 8 days. Both last shipped on September 21, 2026.
