# PDF Book Reader vs Dark Reader

The clearest difference is rating: Dark Reader at 4.4 against PDF Book Reader's 3.9. Dark Reader also leads on ads (none vs shown). PDF Book Reader's advantage is review sentiment (61% vs 30%) and update cadence (every 5 days vs every 2 months). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. PDF Book Reader sells 2 in-app purchases, starting at $3.99 per month and Dark Reader sells 2 in-app purchases, starting at $4.99 per year. Whichever you choose, the download price is not the number that matters.

Dark Reader holds the better App Store score, 4.4 against 3.9. Both are backed by a comparable volume of ratings — 31 and 7 respectively. Written reviews complicate that: 61% of PDF Book Reader'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 Book Reader ships an update every 5 days, Dark Reader every 2 months. The most recent releases landed on September 30, 2026 and September 28, 2026 respectively.
