# Spectrum Analyzer vs BassBox Reflex Pro

The clearest difference is price: Spectrum Analyzer at Free against BassBox Reflex Pro's $3.99. Spectrum Analyzer also leads on rating (4.2 vs 1.8) and update cadence (fortnightly vs every 8 months). BassBox Reflex Pro's advantage is in-app purchases (none vs 13) and ads (none vs shown). On device support there is nothing between them.

Spectrum Analyzer is free to download; BassBox Reflex Pro costs $3.99 up front. Spectrum Analyzer sells 13 in-app purchases, starting at $4.99 per 7 days. BassBox Reflex Pro asks for nothing beyond the download.

Spectrum Analyzer holds the better App Store score, 4.2 against 1.8. That said, the two scores are not equally well evidenced: Spectrum Analyzer has 198 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 5% of Spectrum Analyzer's written reviews are positive against 17% of BassBox Reflex Pro's, so the app with the better star average is not the one people write more warmly about.

Spectrum Analyzer ships an update fortnightly, BassBox Reflex Pro every 8 months. The most recent releases landed on October 19, 2026 and October 6, 2026 respectively.
