# Sixfast vs PDF Scanner

The clearest difference is rating: PDF Scanner at 5.0 against Sixfast's 4.4. PDF Scanner also leads on update cadence (weekly vs every 3 weeks) and iOS requirement (13.0 vs 15.0). Sixfast's advantage is ads (none vs shown) and ratings volume (220 vs 1). On price, in-app purchases and monetization model there is nothing between them.

Both are free to download. Sixfast sells 19 in-app purchases, starting at $5.99 per month and PDF Scanner sells 31 in-app purchases, starting at $0.99 per 7 days. Whichever you choose, the download price is not the number that matters.

PDF Scanner holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Sixfast has 220 ratings behind it against 1, so its average is the more settled of the two.

Sixfast ships an update every 3 weeks, PDF Scanner weekly. The most recent releases landed on September 25, 2026 and August 21, 2026 respectively.
