# DS Scanner vs PDF Reader

The clearest difference is review sentiment: PDF Reader at 50% against DS Scanner's 6%. PDF Reader also leads on rating (4.0 vs 3.6) and update cadence (every 4 days vs every 3 weeks). DS Scanner's advantage is ratings volume (20 vs 4). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. DS Scanner sells 5 in-app purchases, starting at $4.99 per 7 days and PDF Reader sells 1 in-app purchase, starting at $19.99 per 7 days. Whichever you choose, the download price is not the number that matters.

PDF Reader holds the better App Store score, 4.0 against 3.6. That said, the two scores are not equally well evidenced: DS Scanner has 20 ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 6% of DS Scanner's written reviews are positive against 50% of PDF Reader's.

DS Scanner ships an update every 3 weeks, PDF Reader every 4 days. The most recent releases landed on September 18, 2026 and September 23, 2026 respectively.
