Verdict

The call

The clearest difference is rating: Sub at 4.4 against StreamLabs's 2.5. Sub also leads on monetization model (ad-supported vs free with in-app purchases) and ratings volume (778 vs 93). On price, review sentiment, update cadence and ads there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Sub holds the better App Store score, 4.4 against 2.5. That said, the two scores are not equally well evidenced: Sub has 778 ratings behind it against 93, so its average is the more settled of the two. Written reviews complicate that: 20% of StreamLabs's written reviews are positive against 15% of Sub's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

StreamLabs ships an update every 3 weeks, Sub every 5 weeks. The most recent releases landed on October 11, 2026 and October 15, 2026 respectively.
