Verdict

The call

The clearest difference is review sentiment: PDF Reader at 47% against PDF Master's 9%. PDF Reader also leads on monetization model (freemium vs subscription) and ads (none vs shown). PDF Master's advantage is rating (4.3 vs 4.0) and update cadence (every 2 weeks vs monthly). On price, ratings volume, in-app purchases and device support there is nothing between them.

Both are free to download. PDF Reader sells 2 in-app purchases, starting at $1.99 per month and PDF Master sells 12 in-app purchases, starting at $0.99 per 7 days. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

PDF Master holds the better App Store score, 4.3 against 4.0. Both are backed by a comparable volume of ratings — 91 and 200 respectively. Written reviews complicate that: 47% of PDF Reader's written reviews are positive against 9% of PDF Master's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

PDF Reader ships an update monthly, PDF Master every 2 weeks. The most recent releases landed on September 8, 2026 and September 14, 2026 respectively.
