# LanguagePro vs PDF Factory Plus

The clearest difference is review sentiment: LanguagePro at 86% against PDF Factory Plus's 25%. LanguagePro also leads on update cadence (every 4 days vs every 26 months) and ratings volume (77 vs 10). PDF Factory Plus's advantage is rating (4.7 vs 4.4). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. LanguagePro sells 4 in-app purchases, starting at $9.99 per month and PDF Factory Plus sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

PDF Factory Plus holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: LanguagePro has 77 ratings behind it against 10, so its average is the more settled of the two. Written reviews complicate that: 86% of LanguagePro's written reviews are positive against 25% of PDF Factory Plus's, so the app with the better star average is not the one people write more warmly about.

LanguagePro ships an update every 4 days, PDF Factory Plus every 26 months. The most recent releases landed on October 7, 2026 and October 2, 2026 respectively.
