# Galaxy Space Simulator 3D vs Spaceflight Simulator

The clearest difference is review sentiment: Spaceflight Simulator at 86% against Galaxy Space Simulator 3D's 40%. Spaceflight Simulator also leads on update cadence (every 9 days vs every 5 months) and rating (4.8 vs 4.4). Galaxy Space Simulator 3D's advantage is iOS requirement (12.0 vs 15.0).
