Verdict
The clearest difference is review sentiment: PDF Reader at 81% against Zip & RAR File Extractor's 28%. PDF Reader also leads on ads (none vs shown). Zip & RAR File Extractor's advantage is rating (4.7 vs 4.5) and ratings volume (28K vs 3.5K). On price, update cadence, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. PDF Reader sells 10 in-app purchases, starting at $2.99 per month and Zip & RAR File Extractor sells 3 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.
Zip & RAR File Extractor holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Zip & RAR File Extractor has 28K ratings behind it against 3.5K, so its average is the more settled of the two. Written reviews complicate that: 81% of PDF Reader's written reviews are positive against 28% of Zip & RAR File Extractor's, so the app with the better star average is not the one people write more warmly about.
PDF Reader ships an update every 2 months, Zip & RAR File Extractor every 6 weeks. Both last shipped on September 24, 2026.
