# BluOS Controller vs 4STREAM

The clearest difference is rating: BluOS Controller at 4.4 against 4STREAM's 2.7. BluOS Controller also leads on ratings volume (5.3K vs 56) and update cadence (monthly vs every 4 months). 4STREAM's advantage is review sentiment (47% vs 39%) and iOS requirement (10.0 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.

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

BluOS Controller holds the better App Store score, 4.4 against 2.7. That said, the two scores are not equally well evidenced: BluOS Controller has 5.3K ratings behind it against 56, so its average is the more settled of the two. Written reviews complicate that: 39% of BluOS Controller's written reviews are positive against 47% of 4STREAM's, so the app with the better star average is not the one people write more warmly about.

BluOS Controller ships an update monthly, 4STREAM every 4 months. The most recent releases landed on September 24, 2026 and August 25, 2026 respectively.
