# Intergalactic Solar System vs AR Gravity

The clearest difference is rating: AR Gravity at 5.0 against Intergalactic Solar System's 4.0. AR Gravity also leads on in-app purchases (none vs 1) and iOS requirement (11.0 vs 13.0). Intergalactic Solar System's advantage is ratings volume (25 vs 3). On price, review sentiment, ads and device support there is nothing between them.

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

AR Gravity 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 3, so its average is the more settled of the two. Written reviews complicate that: 70% of Intergalactic Solar System's written reviews are positive against 67% of AR Gravity's, so the app with the better star average is not the one people write more warmly about.
