# PDF Max vs Ink PDF Editor

The clearest difference is in-app purchases: Ink PDF Editor at none against PDF Max's 10. Ink PDF Editor also leads on review sentiment (44% vs 35%) and iOS requirement (12.0 vs 18.0). PDF Max's advantage is rating (4.5 vs 4.2) and ratings volume (1.2K vs 37). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. PDF Max sells 10 in-app purchases, starting at $1.99 per 7 days. Ink PDF Editor asks for nothing beyond the download.

PDF Max holds the better App Store score, 4.5 against 4.2. That said, the two scores are not equally well evidenced: PDF Max has 1.2K ratings behind it against 37, so its average is the more settled of the two. Written reviews complicate that: 35% of PDF Max's written reviews are positive against 44% of Ink PDF Editor's, so the app with the better star average is not the one people write more warmly about.

PDF Max ships an update monthly, Ink PDF Editor every 3 weeks. The most recent releases landed on November 6, 2026 and November 3, 2026 respectively.
