# 3D Solar System vs Astronomy Game

3D Solar System and Astronomy Game both sit at 4.4 stars, but that hides the real split: 86% of Astronomy Game's written reviews are positive against 29% of 3D Solar System's. Astronomy Game also leads on ads (none vs shown). 3D Solar System's advantage is update cadence (fortnightly vs every 13 months) and ratings volume (1.7K vs 10). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. 3D Solar System sells 10 in-app purchases, starting at $9.99 per month and Astronomy Game sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.4 for 3D Solar System against 4.4 for Astronomy Game. That said, the two scores are not equally well evidenced: 3D Solar System has 1.7K ratings behind it against 10, so its average is the more settled of the two. Written reviews are what separate them: 29% of 3D Solar System's written reviews are positive against 86% of Astronomy Game's.

3D Solar System ships an update fortnightly, Astronomy Game every 13 months. The most recent releases landed on November 12, 2026 and November 7, 2026 respectively.
