Verdict
The clearest difference is review sentiment: dB Meter at 100% against Frequency Analyzer's 10%. Frequency Analyzer's advantage is ads (none vs shown) and update cadence (every 8 days vs every 3 months). On price, in-app purchases, monetization model and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Frequency Analyzer sells 11 in-app purchases, starting at $2.99 per 7 days and dB Meter sells 4 in-app purchases, starting at $1.99 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 4.3. That said, the two scores are not equally well evidenced: Frequency Analyzer has 169 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 10% of Frequency Analyzer's written reviews are positive against 100% of dB Meter's, so the app with the better star average is not the one people write more warmly about.
Frequency Analyzer ships an update every 8 days, dB Meter every 3 months. Both last shipped on October 16, 2026.
