Verdict

The call

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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.
