# PDF Document Scanner vs Flex Scanner

The clearest difference is rating: Flex Scanner at 4.5 against PDF Document Scanner's 3.8. Flex Scanner also leads on ads (none vs shown) and update cadence (every 9 days vs every 2 months). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. PDF Document Scanner sells 1 one-off in-app purchase and Flex Scanner sells 3 in-app purchases, starting at $0.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Flex Scanner holds the better App Store score, 4.5 against 3.8. That said, the two scores are not equally well evidenced: Flex Scanner has 25 ratings behind it against 5, so its average is the more settled of the two.

PDF Document Scanner ships an update every 2 months, Flex Scanner every 9 days. The most recent releases landed on September 12, 2026 and June 4, 2026 respectively.
