# Decibel Meter vs Frequency Analyzer

The clearest difference is ratings volume: Decibel Meter at 6 against Frequency Analyzer's 1. On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Decibel Meter sells 4 in-app purchases, starting at $8.99 per 7 days and Frequency Analyzer sells 2 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Frequency Analyzer holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Decibel Meter has 6 ratings behind it against 1, so its average is the more settled of the two.

Decibel Meter ships an update weekly, Frequency Analyzer fortnightly. Both last shipped on October 28, 2026.
