# PDF Pro vs OpenDocument Reader

The clearest difference is in-app purchases: OpenDocument Reader at none against PDF Pro's 12. OpenDocument Reader also leads on update cadence (every 4 weeks vs every 2 months) and iOS requirement (15.0 vs 17.0). PDF Pro's advantage is ads (none vs shown) and review sentiment (60% vs 30%). On price 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. OpenDocument Reader asks for nothing beyond the download.

PDF Pro holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: PDF Pro has 6.9K ratings behind it against 905, 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 30% of OpenDocument Reader's.

PDF Pro ships an update every 2 months, OpenDocument Reader every 4 weeks. The most recent releases landed on October 8, 2026 and October 10, 2026 respectively.
