Verdict
Unstoppable Domains and Polygon ID both sit at 4.5 stars, but that hides the real split: 100% of Polygon ID's written reviews are positive against 44% of Unstoppable Domains's. Polygon ID also leads on device support (3 vs 1) and iOS requirement (14.0 vs 16.0). Unstoppable Domains's advantage is ratings volume (185 vs 7). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Unstoppable Domains holds the better App Store score, 4.5 against 4.3. That said, the two scores are not equally well evidenced: Unstoppable Domains has 185 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 44% of Unstoppable Domains's written reviews are positive against 100% of Polygon ID's, so the app with the better star average is not the one people write more warmly about.
Unstoppable Domains ships an update fortnightly, Polygon ID every 3 weeks. The most recent releases landed on October 23, 2026 and October 11, 2026 respectively.
