# PDF Reader Pro vs Dark Reader

The clearest difference is review sentiment: PDF Reader Pro at 100% against Dark Reader's 30%. PDF Reader Pro also leads on in-app purchases (none vs 2). Dark Reader's advantage is rating (4.4 vs 3.6) and ads (none vs shown). On price, ratings volume, update cadence and device support there is nothing between them.

Both are free to download. Dark Reader sells 2 in-app purchases, starting at $4.99 per year. PDF Reader Pro asks for nothing beyond the download.

Dark Reader holds the better App Store score, 4.4 against 3.6. Both are backed by a comparable volume of ratings — 8 and 7 respectively. Written reviews complicate that: 100% of PDF Reader Pro's written reviews are positive against 30% of Dark Reader's, so the app with the better star average is not the one people write more warmly about.

PDF Reader Pro ships an update every 4 months, Dark Reader every 2 months. Both last shipped on September 28, 2026.
