Verdict

The call

The clearest difference is rating: Scanner Pro at 4.9 against Smart PDF Document Scanner's 4.4. Scanner Pro also leads on ads (none vs shown) and update cadence (fortnightly vs every 5 months). Smart PDF Document Scanner's advantage is in-app purchases (none vs 15) and review sentiment (100% vs 80%). On price and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Scanner Pro holds the better App Store score, 4.9 against 4.4. That said, the two scores are not equally well evidenced: Scanner Pro has 335K ratings behind it against 10, so its average is the more settled of the two. Written reviews complicate that: 80% of Scanner Pro's written reviews are positive against 100% of Smart PDF Document Scanner's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Scanner Pro ships an update fortnightly, Smart PDF Document Scanner every 5 months. The most recent releases landed on September 27, 2026 and August 16, 2026 respectively.
