Verdict
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.
