# PDF Pro vs Ink PDF Editor

The clearest difference is rating: PDF Pro at 4.7 against Ink PDF Editor's 4.1. PDF Pro also leads on ratings volume (6.9K vs 35) and review sentiment (60% vs 44%). Ink PDF Editor's advantage is in-app purchases (none vs 12) and update cadence (every 3 weeks vs every 2 months). On price, ads and device support there is nothing between them.

Both are free to download. PDF Pro sells 12 in-app purchases, starting at $1.99 per month. Ink PDF Editor asks for nothing beyond the download.

PDF Pro holds the better App Store score, 4.7 against 4.1. That said, the two scores are not equally well evidenced: PDF Pro has 6.9K ratings behind it against 35, so its average is the more settled of the two. Written reviews point the same way: 60% of PDF Pro's written reviews are positive against 44% of Ink PDF Editor's.

PDF Pro ships an update every 2 months, Ink PDF Editor every 3 weeks. The most recent releases landed on September 24, 2026 and September 17, 2026 respectively.
