# Spectrum Analyzer vs GradedBlue Music

The clearest difference is review sentiment: GradedBlue Music at 100% against Spectrum Analyzer's 5%. GradedBlue Music also leads on rating (5.0 vs 4.2) and ads (none vs shown). Spectrum Analyzer's advantage is ratings volume (197 vs 2) and update cadence (fortnightly vs every 5 weeks). On price, in-app purchases, monetization model and device support 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 GradedBlue Music sells 3 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

GradedBlue Music holds the better App Store score, 5.0 against 4.2. 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 point the same way: 5% of Spectrum Analyzer's written reviews are positive against 100% of GradedBlue Music's.

Spectrum Analyzer ships an update fortnightly, GradedBlue Music every 5 weeks. The most recent releases landed on September 26, 2026 and June 1, 2026 respectively.
