# viewshape vs Onshape 3D CAD

The clearest difference is rating: Onshape 3D CAD at 3.5 against viewshape's 2.7. Onshape 3D CAD also leads on update cadence (every 3 weeks vs every 4 months) and ratings volume (416 vs 3). viewshape's advantage is review sentiment (83% vs 47%) and monetization model (free vs free with in-app purchases). On price, ads, 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.

Onshape 3D CAD holds the better App Store score, 3.5 against 2.7. That said, the two scores are not equally well evidenced: Onshape 3D CAD has 416 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 83% of viewshape's written reviews are positive against 47% of Onshape 3D CAD's, so the app with the better star average is not the one people write more warmly about.
