ReceptionRating · Positive reviews · Number of ratings

Gun Builder 3D! holds the better App Store score, 4.7 against 3.6. That said, the two scores are not equally well evidenced: Gun Builder 3D! has 4.5K ratings behind it against 25, so its average is the more settled of the two. Written reviews complicate that: 100% of Model Constructor 3D's written reviews are positive against 53% of Gun Builder 3D!'s, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Model Constructor 3D ships an update every 2 months, Gun Builder 3D! fortnightly. The most recent releases landed on October 15, 2026 and October 16, 2026 respectively.
