# Atomus 3D vs Particle Simulation

Particle Simulation holds the better App Store score, 4.5 against 4.1. Both are backed by a comparable volume of ratings — 27 and 46 respectively. Written reviews complicate that: 65% of Atomus 3D'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.
