# PDF Scanner Document Convert + vs Redd

The clearest difference is review sentiment: Redd at 75% against PDF Scanner Document Convert +'s 50%. Redd also leads on monetization model (free vs free with in-app purchases) and update cadence (weekly vs every 2 weeks). PDF Scanner Document Convert +'s advantage is ratings volume (97 vs 4) and rating (4.5 vs 4.3). On price, ads and in-app purchases there is nothing between them.

Both are free to download. PDF Scanner Document Convert + sells 3 in-app purchases, starting at $4.99 per 7 days and Redd sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

PDF Scanner Document Convert + holds the better App Store score, 4.5 against 4.3. That said, the two scores are not equally well evidenced: PDF Scanner Document Convert + has 97 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 50% of PDF Scanner Document Convert +'s written reviews are positive against 75% of Redd's, so the app with the better star average is not the one people write more warmly about.

PDF Scanner Document Convert + ships an update every 2 weeks, Redd weekly. The most recent releases landed on September 22, 2026 and September 19, 2026 respectively.
