# AR Gravity vs DIY Solar System

The clearest difference is rating: AR Gravity at 5.0 against DIY Solar System's 4.5. DIY Solar System's advantage is review sentiment (100% vs 67%) and ratings volume (16 vs 3). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

AR Gravity holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: DIY Solar System has 16 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 67% of AR Gravity's written reviews are positive against 100% of DIY Solar System's, so the app with the better star average is not the one people write more warmly about.
