Verdict

The call

The clearest difference is rating: KeeNotes at 5.0 against Scan Things's 3.9. KeeNotes also leads on update cadence (every 9 days vs every 6 weeks) and iOS requirement (15.0 vs 17.6). Scan Things's advantage is monetization model (free vs freemium) and ratings volume (7 vs 1). On price, ads, in-app purchases and device support there is nothing between them.
