# 3D Solar System vs Daff Moon

The clearest difference is review sentiment: Daff Moon at 100% against 3D Solar System's 29%. Daff Moon also leads on rating (4.9 vs 4.4). 3D Solar System's advantage is ratings volume (1.7K vs 19). On price, update cadence, ads and in-app purchases 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 Daff Moon sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Daff Moon holds the better App Store score, 4.9 against 4.4. That said, the two scores are not equally well evidenced: 3D Solar System has 1.7K ratings behind it against 19, 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 100% of Daff Moon's.

3D Solar System ships an update fortnightly, Daff Moon every 2 weeks. The most recent releases landed on November 1, 2026 and October 24, 2026 respectively.
