# Planet simulation vs Water Box

The clearest difference is rating: Water Box at 4.8 against Planet simulation's 3.9. Water Box also leads on update cadence (every 11 days vs every 8 months) and review sentiment (93% vs 74%). Planet simulation's advantage is in-app purchases (none vs 10) and iOS requirement (13.0 vs 15.6). On price, ads and device support there is nothing between them.
