# IQ Test vs Particle Simulation

The clearest difference is price: Particle Simulation at Free against IQ Test's $7.99. Particle Simulation also leads on rating (4.5 vs 1.0) and review sentiment (25% vs 0%). IQ Test's advantage is update cadence (monthly vs every 7 months). On ads, in-app purchases, device support and iOS requirement there is nothing between them.

Particle Simulation is free to download; IQ Test costs $7.99 up front. IQ Test sells 1 one-off in-app purchase 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 1.0. That said, the two scores are not equally well evidenced: Particle Simulation has 46 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 0% of IQ Test's written reviews are positive against 25% of Particle Simulation's.
