# Spectrum Analyzer vs Audio Visualize

The clearest difference is review sentiment: Audio Visualize at 64% against Spectrum Analyzer's 5%. Audio Visualize also leads on update cadence (every 2 days vs fortnightly). Spectrum Analyzer's advantage is rating (4.2 vs 3.8) and ratings volume (199 vs 11). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Spectrum Analyzer sells 13 in-app purchases, starting at $4.99 per 7 days and Audio Visualize sells 3 in-app purchases, starting at $1.99 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 3.8. That said, the two scores are not equally well evidenced: Spectrum Analyzer has 199 ratings behind it against 11, so its average is the more settled of the two. Written reviews complicate that: 5% of Spectrum Analyzer's written reviews are positive against 64% of Audio Visualize's, so the app with the better star average is not the one people write more warmly about.

Spectrum Analyzer ships an update fortnightly, Audio Visualize every 2 days. The most recent releases landed on October 26, 2026 and October 27, 2026 respectively.
