Verdict

The call

The clearest difference is ads: Scanner Pro at none against OneScanner's shown. Scanner Pro also leads on ratings volume (335K vs 16) and rating (4.9 vs 4.6). OneScanner's advantage is review sentiment (100% vs 80%) and iOS requirement (12.0 vs 18.0). On price, update cadence, in-app purchases and monetization model there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. Scanner Pro sells 11 in-app purchases, starting at $3.99 per month and OneScanner sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Scanner Pro holds the better App Store score, 4.9 against 4.6. That said, the two scores are not equally well evidenced: Scanner Pro has 335K ratings behind it against 16, 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 OneScanner'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, OneScanner every 3 weeks. The most recent releases landed on September 26, 2026 and June 11, 2026 respectively.
