# soundOscope vs Spectrum Analyzer

The clearest difference is review sentiment: soundOscope at 55% against Spectrum Analyzer's 5%. soundOscope also leads on ads (none vs shown) and iOS requirement (14.0 vs 16.0). Spectrum Analyzer's advantage is rating (4.2 vs 2.4) and update cadence (fortnightly vs every 39 months). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. soundOscope sells 1 one-off in-app purchase 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 2.4. That said, the two scores are not equally well evidenced: Spectrum Analyzer has 197 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 55% of soundOscope'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.

soundOscope ships an update every 39 months, Spectrum Analyzer fortnightly. The most recent releases landed on October 8, 2026 and October 11, 2026 respectively.
