Verdict
The clearest difference is review sentiment: PDF Reader at 81% against The Document Converter's 36%. PDF Reader also leads on update cadence (every 2 months vs every 5 months) and iOS requirement (13.0 vs 15.6). The Document Converter's advantage is rating (4.7 vs 4.5). On price, ratings volume, ads and in-app purchases 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 The Document Converter sells 5 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
The Document Converter holds the better App Store score, 4.7 against 4.5. Both are backed by a comparable volume of ratings — 3.5K and 5.9K respectively. Written reviews complicate that: 81% of PDF Reader's written reviews are positive against 36% of The Document Converter'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, The Document Converter every 5 months. The most recent releases landed on September 24, 2026 and September 22, 2026 respectively.
