Read the TOS and per scan pricing – Qlone 3D Scanner Review

I won’t fault ease of use as the problem with this app. They own your scanned work without owning it. Read the TOS as you’re providing them a library of content to do what they will with. Regarding the pricing, you don’t unlock unlimited scans, but the ability to export a single scanned object. Save your money and effort for a desktop based scanning solution.
