# SecureZIP Reader vs PDF Reader

The clearest difference is rating: PDF Reader at 4.7 against SecureZIP Reader's 3.0. PDF Reader also leads on update cadence (every 8 days vs every 7 months) and ratings volume (665 vs 5). SecureZIP Reader's advantage is in-app purchases (none vs 11) and ads (none vs shown). On price and device support there is nothing between them.

Both are free to download. PDF Reader sells 9 in-app purchases, starting at $3.99 per 7 days. SecureZIP Reader asks for nothing beyond the download.

PDF Reader holds the better App Store score, 4.7 against 3.0. That said, the two scores are not equally well evidenced: PDF Reader has 665 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 69% of SecureZIP Reader's written reviews are positive against 37% of PDF Reader's, so the app with the better star average is not the one people write more warmly about.

SecureZIP Reader ships an update every 7 months, PDF Reader every 8 days. The most recent releases landed on September 3, 2026 and September 23, 2026 respectively.
