Verdict

The call

The clearest difference is review sentiment: Authenticator App at 67% against Scanner App's 17%. Scanner App's advantage is rating (4.9 vs 4.3) and update cadence (every 2 weeks vs every 8 months). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Scanner App sells 6 in-app purchases, starting at $2.99 per 3 months and Authenticator App sells 15 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Scanner App holds the better App Store score, 4.9 against 4.3. Both are backed by a comparable volume of ratings — 307 and 210 respectively. Written reviews complicate that: 17% of Scanner App's written reviews are positive against 67% of Authenticator App's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Scanner App ships an update every 2 weeks, Authenticator App every 8 months. Both last shipped on September 28, 2026.
