Verdict
The clearest difference is price: Spectrum Analyzer at Free against Spectre's $0.99. Spectrum Analyzer also leads on rating (4.2 vs 3.0) and update cadence (fortnightly vs every 96 months). Spectre's advantage is review sentiment (40% vs 5%) and in-app purchases (none vs 13). 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; Spectre costs $0.99 up front. Spectrum Analyzer sells 13 in-app purchases, starting at $4.99 per 7 days. Spectre asks for nothing beyond the download.
Spectrum Analyzer holds the better App Store score, 4.2 against 3.0. That said, the two scores are not equally well evidenced: Spectrum Analyzer has 197 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 40% of Spectre'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.
Spectre ships an update every 96 months, Spectrum Analyzer fortnightly. The most recent releases landed on September 6, 2026 and September 24, 2026 respectively.
