Verdict
The clearest difference is price: Spectrum Analyzer at Free against Frequency Meter PRO's $2.99. Spectrum Analyzer also leads on rating (4.2 vs 1.8) and update cadence (fortnightly vs every 4 months). Frequency Meter PRO's advantage is in-app purchases (none vs 13) and ads (none vs shown). On 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
Spectrum Analyzer is free to download; Frequency Meter PRO costs $2.99 up front. Spectrum Analyzer sells 13 in-app purchases, starting at $4.99 per 7 days. Frequency Meter PRO asks for nothing beyond the download.
Spectrum Analyzer holds the better App Store score, 4.2 against 1.8. That said, the two scores are not equally well evidenced: Spectrum Analyzer has 197 ratings behind it against 30, so its average is the more settled of the two. Written reviews complicate that: 15% of Frequency Meter PRO's written reviews are positive against 5% of Spectrum Analyzer's, so the app with the better star average is not the one people write more warmly about.
Frequency Meter PRO ships an update every 4 months, Spectrum Analyzer fortnightly. Both last shipped on September 24, 2026.
