# Fast Scan vs PDF

The clearest difference is review sentiment: PDF at 89% against Fast Scan's 11%. PDF also leads on rating (4.8 vs 3.5) and monetization model (free with in-app purchases vs subscription). Fast Scan's advantage is iOS requirement (10.0 vs 13.0). On price, ratings volume, in-app purchases and device support there is nothing between them.

Both are free to download. Fast Scan sells 10 in-app purchases, starting at $1.99 per 7 days and PDF sells 3 in-app purchases, starting at $0.99 per 7 days. Whichever you choose, the download price is not the number that matters.

PDF holds the better App Store score, 4.8 against 3.5. Both are backed by a comparable volume of ratings — 321 and 115 respectively. Written reviews point the same way: 11% of Fast Scan's written reviews are positive against 89% of PDF's.

Fast Scan ships an update every 5 weeks, PDF fortnightly. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
