# Analyzer vs Spectrum Analyzer

The clearest difference is price: Spectrum Analyzer at Free against Analyzer's $14.99. Spectrum Analyzer also leads on rating (4.2 vs 2.9) and update cadence (fortnightly vs every 6 weeks). Analyzer's advantage is review sentiment (49% vs 5%) and ads (none vs shown). On in-app purchases, monetization model and device support there is nothing between them.

Spectrum Analyzer is free to download; Analyzer costs $14.99 up front. Analyzer sells 10 one-off in-app purchases and Spectrum Analyzer sells 13 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Spectrum Analyzer holds the better App Store score, 4.2 against 2.9. That said, the two scores are not equally well evidenced: Spectrum Analyzer has 197 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 5% of Spectrum Analyzer's, so the app with the better star average is not the one people write more warmly about.

Analyzer ships an update every 6 weeks, Spectrum Analyzer fortnightly. The most recent releases landed on September 24, 2026 and September 26, 2026 respectively.
