# Sketch 3D Modeling vs 3D看图

Sketch 3D Modeling and 3D看图 are too close to call on the numbers: across 6 compared parameters — price, update cadence, ads and in-app purchases among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

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

Sketch 3D Modeling ships an update every 5 weeks, 3D看图 every 3 weeks. The most recent releases landed on May 19, 2026 and September 21, 2026 respectively.
