Verdict

The call

Lextra and PDF Book Reader both sit at 4.1 stars, but that hides the real split: 63% of PDF Book Reader's written reviews are positive against 22% of Lextra's. PDF Book Reader also leads on update cadence (every 5 days vs fortnightly) and iOS requirement (13.0 vs 26). Lextra's advantage is ratings volume (971 vs 32). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Lextra sells 10 in-app purchases, starting at $4.99 per month and PDF Book Reader sells 2 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Lextra holds the better App Store score, 4.1 against 3.9. That said, the two scores are not equally well evidenced: Lextra has 971 ratings behind it against 32, so its average is the more settled of the two. Written reviews complicate that: 22% of Lextra's written reviews are positive against 63% of PDF Book Reader's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Lextra ships an update fortnightly, PDF Book Reader every 5 days. The most recent releases landed on November 6, 2026 and November 3, 2026 respectively.
