# Frequency Analyzer vs Resonance

The clearest difference is rating: Resonance at 5.0 against Frequency Analyzer's 4.5. Resonance also leads on device support (3 vs 1) and iOS requirement (15.6 vs 17.2). Frequency Analyzer's advantage is update cadence (every 8 days vs every 4 months) and ratings volume (169 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Frequency Analyzer sells 11 in-app purchases, starting at $2.99 per 7 days and Resonance sells 3 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

Resonance holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Frequency Analyzer has 169 ratings behind it against 1, so its average is the more settled of the two.

Frequency Analyzer ships an update every 8 days, Resonance every 4 months. The most recent releases landed on October 13, 2026 and October 10, 2026 respectively.
