# Fast PDF Reader & Converter vs PDF AI Scanner

The clearest difference is in-app purchases: Fast PDF Reader & Converter at none against PDF AI Scanner's 3. Fast PDF Reader & Converter also leads on review sentiment (100% vs 71%). PDF AI Scanner's advantage is rating (4.6 vs 4.3) and iOS requirement (13.0 vs 15.6). On price, ratings volume, update cadence and ads there is nothing between them.

PDF AI Scanner holds the better App Store score, 4.6 against 4.3. Both are backed by a comparable volume of ratings — 19 and 12 respectively. Written reviews complicate that: 100% of Fast PDF Reader & Converter's written reviews are positive against 71% of PDF AI Scanner's, so the app with the better star average is not the one people write more warmly about.
