# Spectrum Analyzer vs PartyPulse

The clearest difference is review sentiment: PartyPulse at 56% against Spectrum Analyzer's 5%. PartyPulse also leads on in-app purchases (none vs 13) and ads (none vs shown). Spectrum Analyzer's advantage is rating (4.2 vs 3.6) and update cadence (fortnightly vs every 35 months). On price there is nothing between them.

Both are free to download. Spectrum Analyzer sells 13 in-app purchases, starting at $4.99 per 7 days. PartyPulse asks for nothing beyond the download.

Spectrum Analyzer holds the better App Store score, 4.2 against 3.6. That said, the two scores are not equally well evidenced: Spectrum Analyzer has 197 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 56% of PartyPulse's, so the app with the better star average is not the one people write more warmly about.

Spectrum Analyzer ships an update fortnightly, PartyPulse every 35 months. The most recent releases landed on October 2, 2026 and September 22, 2026 respectively.
