# Sure vs AES Opyn

The clearest difference is rating: Sure at 3.7 against AES Opyn's 2.5. Sure also leads on update cadence (every 6 weeks vs every 4 months) and iOS requirement (13 vs 15.0). AES Opyn's advantage is review sentiment (33% vs 0%). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Sure holds the better App Store score, 3.7 against 2.5. Both are backed by a comparable volume of ratings — 3 and 6 respectively. Written reviews complicate that: 0% of Sure's written reviews are positive against 33% of AES Opyn's, so the app with the better star average is not the one people write more warmly about.

Sure ships an update every 6 weeks, AES Opyn every 4 months. Both last shipped on October 24, 2026.
