# Scanner Pro vs One Scan

The clearest difference is review sentiment: Scanner Pro at 80% against One Scan's 26%. Scanner Pro also leads on update cadence (fortnightly vs every 2 months) and ratings volume (335K vs 12K). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Scanner Pro sells 11 in-app purchases, starting at $3.99 per month and One Scan sells 10 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Scanner Pro holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: Scanner Pro has 335K ratings behind it against 12K, so its average is the more settled of the two. Written reviews point the same way: 80% of Scanner Pro's written reviews are positive against 26% of One Scan's.

Scanner Pro ships an update fortnightly, One Scan every 2 months. Both last shipped on September 24, 2026.
