Verdict

The call

The clearest difference is review sentiment: Scan 2 PDF at 100% against One Scan's 26%. Scan 2 PDF also leads on update cadence (every 10 days vs every 2 months) and rating (5.0 vs 4.7). One Scan's advantage is ads (none vs shown) and ratings volume (12K vs 2). On price, in-app purchases, monetization model and device support there is nothing between them.
