Verdict
The clearest difference is review sentiment: Model Constructor 3D at 100% against RADS4KIDS's 50%. Model Constructor 3D also leads on update cadence (every 2 months vs every 22 months) and ratings volume (25 vs 2). RADS4KIDS's advantage is ads (none vs shown) and rating (4.0 vs 3.6). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
RADS4KIDS holds the better App Store score, 4.0 against 3.6. That said, the two scores are not equally well evidenced: Model Constructor 3D has 25 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 50% of RADS4KIDS's written reviews are positive against 100% of Model Constructor 3D's, so the app with the better star average is not the one people write more warmly about.
RADS4KIDS ships an update every 22 months, Model Constructor 3D every 2 months. The most recent releases landed on November 1, 2026 and November 2, 2026 respectively.
