Verdict

The call

Universe Gravity Simulator 3D and Planet Explorers both sit at 4.0 stars, but that hides the real split: 100% of Planet Explorers's written reviews are positive against 43% of Universe Gravity Simulator 3D's. Planet Explorers also leads on in-app purchases (none vs 1) and update cadence (every 5 days vs every 5 weeks). Universe Gravity Simulator 3D's advantage is ratings volume (136 vs 1) and iOS requirement (12.0 vs 26.0). On price, rating, ads and device support there is nothing between them.
