# PDF Expert vs MobiPDF・PDF Text Editor・Reader

PDF Expert's advantage is ratings volume (216K vs 7.3K) and iOS requirement (16.0 vs 18.0). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. PDF Expert sells 10 in-app purchases, starting at $9.99 per month and MobiPDF・PDF Text Editor・Reader sells 13 in-app purchases, starting at $7.99 per 7 days. Whichever you choose, the download price is not the number that matters.

That said, the two scores are not equally well evidenced: PDF Expert has 216K ratings behind it against 7.3K, so its average is the more settled of the two.
