# Quantum Frequency vs Noise Generator

The clearest difference is rating: Noise Generator at 4.7 against Quantum Frequency's 4.1. Noise Generator also leads on update cadence (fortnightly vs every 7 months) and ratings volume (2K vs 7). Quantum Frequency's advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). On price, review sentiment, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Noise Generator holds the better App Store score, 4.7 against 4.1. That said, the two scores are not equally well evidenced: Noise Generator has 2K ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 80% of Quantum Frequency's written reviews are positive against 75% of Noise Generator's, so the app with the better star average is not the one people write more warmly about.

Quantum Frequency ships an update every 7 months, Noise Generator fortnightly. The most recent releases landed on October 24, 2026 and October 21, 2026 respectively.
