# Intergalactic Solar System vs Orbital Simulator

The clearest difference is rating: Orbital Simulator at 5.0 against Intergalactic Solar System's 4.0. Orbital Simulator also leads on in-app purchases (none vs 1) and update cadence (fortnightly vs monthly). Intergalactic Solar System's advantage is ads (none vs shown) and ratings volume (25 vs 5). On price, device support and iOS requirement there is nothing between them.

Both are free to download. Intergalactic Solar System sells 1 one-off in-app purchase. Orbital Simulator asks for nothing beyond the download.

Orbital Simulator holds the better App Store score, 5.0 against 4.0. That said, the two scores are not equally well evidenced: Intergalactic Solar System has 25 ratings behind it against 5, so its average is the more settled of the two.
