# Gravity Free vs Particle Simulation

The clearest difference is review sentiment: Gravity Free at 72% against Particle Simulation's 25%. Gravity Free also leads on iOS requirement (8.0 vs 12.0). Particle Simulation's advantage is rating (4.5 vs 4.2). On price, ratings volume, update cadence and ads there is nothing between them.

Both are free to download. Gravity Free 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 4.2. Both are backed by a comparable volume of ratings — 92 and 46 respectively. Written reviews complicate that: 72% of Gravity Free'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.

Gravity Free ships an update every 11 months, Particle Simulation every 7 months. The most recent releases landed on September 19, 2026 and September 9, 2026 respectively.
