# Vibroscope vs Sound Spectrum Analysis

The clearest difference is price: Sound Spectrum Analysis at Free against Vibroscope's $7.99. Sound Spectrum Analysis also leads on update cadence (every 5 weeks vs every 8 months) and review sentiment (60% vs 40%). Vibroscope's advantage is rating (5.0 vs 3.6) and in-app purchases (none vs 1). On ads and device support there is nothing between them.

Sound Spectrum Analysis is free to download; Vibroscope costs $7.99 up front. Sound Spectrum Analysis sells 1 one-off in-app purchase. Vibroscope asks for nothing beyond the download.

Vibroscope holds the better App Store score, 5.0 against 3.6. That said, the two scores are not equally well evidenced: Sound Spectrum Analysis has 42 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 40% of Vibroscope's written reviews are positive against 60% of Sound Spectrum Analysis's, so the app with the better star average is not the one people write more warmly about.

Vibroscope ships an update every 8 months, Sound Spectrum Analysis every 5 weeks. The most recent releases landed on October 26, 2026 and October 22, 2026 respectively.
