Verdict
The clearest difference is price: Spaceflight Simulator at Free against Interloper's $1.99. Spaceflight Simulator also leads on ratings volume (98K vs 533) and rating (4.8 vs 4.5). Interloper's advantage is in-app purchases (none vs 11) and iOS requirement (13.0 vs 15.0). On update cadence, ads and device support there is nothing between them.
