Both are free to download. PDF Reader sells 1 one-off in-app purchase. Polaris PDF Viewer asks for nothing beyond the download.
Polaris PDF Viewer holds the better App Store score, 4.4 against 3.5. That said, the two scores are not equally well evidenced: Polaris PDF Viewer has 49 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 33% of PDF Reader's written reviews are positive against 0% of Polaris PDF Viewer's, so the app with the better star average is not the one people write more warmly about.
PDF Reader ships an update every 9 months, Polaris PDF Viewer every 5 weeks. The most recent releases landed on October 2, 2026 and October 26, 2026 respectively.
