Verdict
The clearest difference is rating: PDF Reader at 4.9 against HiReader's 4.4. PDF Reader also leads on iOS requirement (12.0 vs 15.5). HiReader's advantage is review sentiment (88% vs 71%) and update cadence (every 9 days vs every 3 weeks). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. PDF Reader sells 5 one-off in-app purchases and HiReader sells 3 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.
PDF Reader holds the better App Store score, 4.9 against 4.4. Both are backed by a comparable volume of ratings — 8 and 10 respectively. Written reviews complicate that: 71% of PDF Reader's written reviews are positive against 88% of HiReader's, so the app with the better star average is not the one people write more warmly about.
PDF Reader ships an update every 3 weeks, HiReader every 9 days. The most recent releases landed on October 8, 2026 and October 12, 2026 respectively.
