Verdict

The call

The clearest difference is ads: Scanner Pro at none against PDF Maker's shown. Scanner Pro also leads on update cadence (fortnightly vs every 5 months) and ratings volume (338K vs 85). PDF Maker's advantage is iOS requirement (12.0 vs 18.0). On price, rating, in-app purchases and monetization model there is nothing between them.
