# PDF Extractor vs OpenCat

The clearest difference is rating: OpenCat at 4.6 against PDF Extractor's 3.0. OpenCat also leads on update cadence (weekly vs every 23 months) and ratings volume (851 vs 2). PDF Extractor's advantage is review sentiment (100% vs 65%) and iOS requirement (15.0 vs 17.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. PDF Extractor sells 1 one-off in-app purchase and OpenCat sells 4 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

OpenCat holds the better App Store score, 4.6 against 3.0. That said, the two scores are not equally well evidenced: OpenCat has 851 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 100% of PDF Extractor's written reviews are positive against 65% of OpenCat's, so the app with the better star average is not the one people write more warmly about.

PDF Extractor ships an update every 23 months, OpenCat weekly. The most recent releases landed on October 24, 2026 and October 27, 2026 respectively.
