# NASA vs 3

NASA and 3 both sit at 4.8 stars, but that hides the real split: 100% of 3's written reviews are positive against 70% of NASA's. NASA's advantage is ratings volume (64K vs 3) and update cadence (every 2 weeks vs monthly). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

3 holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: NASA has 64K ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 70% of NASA's written reviews are positive against 100% of 3's.

NASA ships an update every 2 weeks, 3 monthly. The most recent releases landed on October 31, 2026 and October 22, 2026 respectively.
