# PDFAI Scan vs LinkBox

The clearest difference is rating: PDFAI Scan at 5.0 against LinkBox's 4.4. LinkBox's advantage is in-app purchases (none vs 3) and review sentiment (80% vs 50%). On price, ratings volume, update cadence and ads there is nothing between them.

Both are free to download. PDFAI Scan sells 3 in-app purchases, starting at $3.99 per 7 days. LinkBox asks for nothing beyond the download.

PDFAI Scan holds the better App Store score, 5.0 against 4.4. Both are backed by a comparable volume of ratings — 7 and 18 respectively. Written reviews complicate that: 50% of PDFAI Scan's written reviews are positive against 80% of LinkBox's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 6 weeks. The most recent releases landed on October 12, 2026 and October 9, 2026 respectively.
