# Grav Box vs Particle World

The clearest difference is ads: Particle World at none against Grav Box's shown. Particle World also leads on iOS requirement (8.0 vs 14.0). Grav Box's advantage is ratings volume (26 vs 1) and update cadence (every 5 months vs every 10 months). On price, rating, review sentiment and in-app purchases there is nothing between them.

Both are free to download. Grav Box sells 10 one-off in-app purchases and Particle World sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Particle World holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Grav Box has 26 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 96% of Grav Box's written reviews are positive against 100% of Particle World's.

Grav Box ships an update every 5 months, Particle World every 10 months. The most recent releases landed on October 24, 2026 and October 22, 2026 respectively.
