Verdict

The call

The clearest difference is ads: PDF Scanner at none against Authenticator's shown. PDF Scanner also leads on ratings volume (243 vs 25). Authenticator's advantage is update cadence (weekly vs fortnightly) and iOS requirement (14.0 vs 16.0). On price, rating, in-app purchases and monetization model there is nothing between them.
