# Hypnotic Spiral vs Particle Simulation

The clearest difference is rating: Particle Simulation at 4.5 against Hypnotic Spiral's 3.4. Particle Simulation also leads on update cadence (every 7 months vs every 43 months). Hypnotic Spiral's advantage is review sentiment (49% vs 25%) and ratings volume (138 vs 46). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Hypnotic Spiral sells 1 one-off in-app purchase and Particle Simulation sells 4 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Particle Simulation holds the better App Store score, 4.5 against 3.4. Both are backed by a comparable volume of ratings — 138 and 46 respectively. Written reviews complicate that: 49% of Hypnotic Spiral's written reviews are positive against 25% of Particle Simulation's, so the app with the better star average is not the one people write more warmly about.

Hypnotic Spiral ships an update every 43 months, Particle Simulation every 7 months. The most recent releases landed on September 26, 2026 and September 9, 2026 respectively.
