Verdict

The call

The clearest difference is ads: Scan Things at none against Zero Scan's shown. Scan Things also leads on device support (3 vs 1). Zero Scan's advantage is update cadence (every 2 days vs every 6 weeks). On price, in-app purchases and iOS requirement there is nothing between them.
