# Stream_Vision vs SiOnyx Aurora

The clearest difference is rating: Stream_Vision at 3.9 against SiOnyx Aurora's 1.9. Stream_Vision also leads on ratings volume (400 vs 42) and iOS requirement (13.0 vs 15.0). On price, review sentiment, 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.

Stream_Vision holds the better App Store score, 3.9 against 1.9. That said, the two scores are not equally well evidenced: Stream_Vision has 400 ratings behind it against 42, so its average is the more settled of the two. Written reviews complicate that: 9% of Stream_Vision's written reviews are positive against 12% of SiOnyx Aurora's, so the app with the better star average is not the one people write more warmly about.

Stream_Vision ships an update every 2 months, SiOnyx Aurora every 3 months. The most recent releases landed on November 6, 2026 and November 2, 2026 respectively.
