Verdict

The call

One Scan and eSign App both sit at 4.7 stars, but that hides the real split: 85% of eSign App's written reviews are positive against 26% of One Scan's. eSign App also leads on update cadence (every 3 weeks vs every 2 months) and chart position (#74 vs unranked). One Scan's advantage is monetization model (freemium vs subscription) and ratings volume (12K vs 1.5K). On price, rating, ads and in-app purchases there is nothing between them.
