# 3D Solar System vs Next Numbers 2

The clearest difference is review sentiment: Next Numbers 2 at 88% against 3D Solar System's 29%. Next Numbers 2 also leads on ads (none vs shown) and rating (4.7 vs 4.4). 3D Solar System's advantage is ratings volume (1.7K vs 31). On price, update cadence, 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 Next Numbers 2 sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Next Numbers 2 holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: 3D Solar System has 1.7K ratings behind it against 31, 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 88% of Next Numbers 2's.
