Verdict
The clearest difference is rating: Petra at 4.8 against Polygon ID's 4.3. Petra also leads on ratings volume (317 vs 7). Polygon ID's advantage is review sentiment (100% vs 75%) and device support (3 vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Petra holds the better App Store score, 4.8 against 4.3. That said, the two scores are not equally well evidenced: Petra has 317 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 100% of Polygon ID's written reviews are positive against 75% of Petra's, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on October 11, 2026 and October 30, 2026 respectively.
