Verdict

The call

The clearest difference is monetization model: Authenticator App at free with in-app purchases against PDF Converter・Scanner・Editor・'s subscription. Authenticator App also leads on review sentiment (62% vs 36%). PDF Converter・Scanner・Editor・'s advantage is update cadence (every 3 weeks vs every 8 months) and rating (4.6 vs 4.3). On price, ratings volume, ads and in-app purchases there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

PDF Converter・Scanner・Editor・ holds the better App Store score, 4.6 against 4.3. Both are backed by a comparable volume of ratings — 152 and 213 respectively.

UpkeepUpdate frequency
