# 3D Solar System vs Under the sun

The clearest difference is rating: 3D Solar System at 4.4 against Under the sun's 2.3. 3D Solar System also leads on review sentiment (29% vs 0%) and ratings volume (1.7K vs 3). Under the sun's advantage is ads (none vs shown) and device support (5 vs 2). On price, in-app purchases, monetization model and iOS requirement there is nothing between them.

Both are free to download. 3D Solar System sells 12 in-app purchases, starting at $7.99 per 7 days and Under the sun sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

3D Solar System holds the better App Store score, 4.4 against 2.3. That said, the two scores are not equally well evidenced: 3D Solar System has 1.7K ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 29% of 3D Solar System's written reviews are positive against 0% of Under the sun's.

3D Solar System ships an update fortnightly, Under the sun every 3 months. Both last shipped on October 24, 2026.
