Verdict

The call

Shapr 3D CAD modeling and InkSpace both sit at 4.7 stars, but that hides the real split: 100% of InkSpace's written reviews are positive against 50% of Shapr 3D CAD modeling's. Shapr 3D CAD modeling's advantage is ratings volume (34K vs 10) and monetization model (free with in-app purchases vs paid). On price, rating, update cadence and ads there is nothing between them.
