# Fractally vs Particle Simulation

The clearest difference is review sentiment: Fractally at 76% against Particle Simulation's 25%. Particle Simulation's advantage is rating (4.5 vs 4.1) and update cadence (every 7 months vs every 25 months). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Fractally sells 9 in-app purchases, starting at $0.99 per year and Particle Simulation sells 4 in-app purchases, starting at $3.99 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 4.1. Both are backed by a comparable volume of ratings — 17 and 46 respectively. Written reviews complicate that: 76% of Fractally'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.

Fractally ships an update every 25 months, Particle Simulation every 7 months. The most recent releases landed on October 7, 2026 and October 8, 2026 respectively.
