# Noise Generator vs Molecule Simulator

The clearest difference is ads: Molecule Simulator at none against Noise Generator's shown. Molecule Simulator also leads on review sentiment (100% vs 75%) and monetization model (free vs free with in-app purchases). Noise Generator's advantage is update cadence (fortnightly vs every 4 months) and ratings volume (2K vs 26). On price, in-app purchases, device support and iOS requirement 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 4.4. That said, the two scores are not equally well evidenced: Noise Generator has 2K ratings behind it against 26, so its average is the more settled of the two. Written reviews complicate that: 75% of Noise Generator's written reviews are positive against 100% of Molecule Simulator's, so the app with the better star average is not the one people write more warmly about.

Noise Generator ships an update fortnightly, Molecule Simulator every 4 months. The most recent releases landed on October 21, 2026 and October 24, 2026 respectively.
