# RedGuard vs PDF Scanner

The clearest difference is ads: RedGuard at none against PDF Scanner's shown. RedGuard also leads on rating (4.6 vs 4.2) and ratings volume (675 vs 17). PDF Scanner's advantage is update cadence (every 9 days vs every 17 months). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. RedGuard sells 3 in-app purchases, starting at $1.99 per 7 days and PDF Scanner sells 3 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.

RedGuard holds the better App Store score, 4.6 against 4.2. That said, the two scores are not equally well evidenced: RedGuard has 675 ratings behind it against 17, so its average is the more settled of the two.

RedGuard ships an update every 17 months, PDF Scanner every 9 days. The most recent releases landed on October 27, 2026 and October 28, 2026 respectively.
