ReceptionRating · Positive reviews · Number of ratings

Fluids & Particle Simulation holds the better App Store score, 4.7 against 3.0. That said, the two scores are not equally well evidenced: Fluids & Particle Simulation has 770 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 90% of Fluids & Particle Simulation's written reviews are positive against 100% of Optical Illusion Pro's, so the app with the better star average is not the one people write more warmly about.
