Verdict

The call

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

Spectre ships an update every 96 months, Spectrum Analyzer fortnightly. The most recent releases landed on September 6, 2026 and September 24, 2026 respectively.
