Verdict

The call

The clearest difference is in-app purchases: 3D Print Doctor at none against Scanner App's 1. 3D Print Doctor also leads on ads (none vs shown). Scanner App's advantage is update cadence (every 3 days vs every 2 weeks). On price, device support and iOS requirement there is nothing between them.
