Verdict

The call

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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