# 3D Solar System vs Space Gate

The clearest difference is review sentiment: Space Gate at 86% against 3D Solar System's 29%. Space Gate also leads on ads (none vs shown) and rating (4.8 vs 4.4). 3D Solar System's advantage is price (Free vs $12.99) and ratings volume (1.7K vs 200). On in-app purchases, monetization model, device support and iOS requirement there is nothing between them.

3D Solar System is free to download; Space Gate costs $12.99 up front. 3D Solar System sells 12 in-app purchases, starting at $7.99 per 7 days and Space Gate sells 3 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

Space Gate holds the better App Store score, 4.8 against 4.4. That said, the two scores are not equally well evidenced: 3D Solar System has 1.7K ratings behind it against 200, 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 86% of Space Gate's.

3D Solar System ships an update fortnightly, Space Gate weekly. The most recent releases landed on September 25, 2026 and August 1, 2026 respectively.
