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.
Stream_Vision holds the better App Store score, 3.9 against 2.0. That said, the two scores are not equally well evidenced: Stream_Vision has 400 ratings behind it against 36, so its average is the more settled of the two. Written reviews complicate that: 9% of Stream_Vision's written reviews are positive against 23% of INREII'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 2 months. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
