# PDF Expert vs D818

The clearest difference is in-app purchases: D818 at none against PDF Expert's 12. D818 also leads on rating (5.0 vs 4.7) and iOS requirement (13.0 vs 16.0). PDF Expert's advantage is ratings volume (216K vs 1) and update cadence (fortnightly vs every 5 weeks). On price, ads and device support there is nothing between them.

Both are free to download. PDF Expert sells 10 in-app purchases, starting at $9.99 per month. D818 asks for nothing beyond the download.

D818 holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: PDF Expert has 216K ratings behind it against 1, so its average is the more settled of the two.

PDF Expert ships an update fortnightly, D818 every 5 weeks. The most recent releases landed on October 14, 2026 and October 1, 2026 respectively.
