Verdict

The call

The clearest difference is price: Audio Spectrum Analyzer dB RTA at Free against Analyzer's $14.99. Audio Spectrum Analyzer dB RTA also leads on rating (4.5 vs 2.9) and ratings volume (3K vs 11). Analyzer's advantage is update cadence (every 6 weeks vs every 5 months) and iOS requirement (12.4 vs 15). On review sentiment, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Audio Spectrum Analyzer dB RTA holds the better App Store score, 4.5 against 2.9. That said, the two scores are not equally well evidenced: Audio Spectrum Analyzer dB RTA has 3K ratings behind it against 11, so its average is the more settled of the two. Written reviews complicate that: 49% of Analyzer's written reviews are positive against 44% of Audio Spectrum Analyzer dB RTA's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Analyzer ships an update every 6 weeks, Audio Spectrum Analyzer dB RTA every 5 months. The most recent releases landed on September 24, 2026 and September 22, 2026 respectively.
