# Polaris Viewer vs 웍스

The clearest difference is in-app purchases: 웍스 at none against Polaris Viewer's 1. 웍스 also leads on ads (none vs shown) and rating (5.0 vs 4.6). Polaris Viewer's advantage is ratings volume (74 vs 1) and device support (4 vs 2). On price and review sentiment there is nothing between them.

Both are free to download. Polaris Viewer sells 1 one-off in-app purchase. 웍스 asks for nothing beyond the download.

웍스 holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Polaris Viewer has 74 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 56% of Polaris Viewer's written reviews are positive against 50% of 웍스's, so the app with the better star average is not the one people write more warmly about.

Polaris Viewer ships an update every 3 months, 웍스 every 6 weeks. The most recent releases landed on October 26, 2026 and October 27, 2026 respectively.
