# Particle Detector vs Frequency Analyzer

The clearest difference is review sentiment: Particle Detector at 100% against Frequency Analyzer's 0%. Particle Detector also leads on in-app purchases (none vs 11) and device support (3 vs 1). Frequency Analyzer's advantage is rating (4.5 vs 4.0) and update cadence (every 8 days vs every 2 months). On price and ads there is nothing between them.

Both are free to download. Frequency Analyzer sells 11 in-app purchases, starting at $2.99 per 7 days. Particle Detector asks for nothing beyond the download.

Frequency Analyzer holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: Frequency Analyzer has 166 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of Particle Detector's written reviews are positive against 0% of Frequency Analyzer's, so the app with the better star average is not the one people write more warmly about.

Particle Detector ships an update every 2 months, Frequency Analyzer every 8 days. The most recent releases landed on June 7, 2026 and September 21, 2026 respectively.
