Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Code Ninjas holds the better App Store score, 4.8 against 2.5. That said, the two scores are not equally well evidenced: Code Ninjas has 1.2K ratings behind it against 32, so its average is the more settled of the two. Written reviews complicate that: 41% of Professor Maxwell’s 4D Galaxy's written reviews are positive against 39% of Code Ninjas's, so the app with the better star average is not the one people write more warmly about.
Professor Maxwell’s 4D Galaxy ships an update every 8 months, Code Ninjas every 5 months. The most recent releases landed on October 4, 2026 and October 12, 2026 respectively.
