ReceptionRating · Positive reviews · Number of ratings

RTMP Broadcaster holds the better App Store score, 4.7 against 4.2. That said, the two scores are not equally well evidenced: RTMP Broadcaster has 30 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 88% of LM's written reviews are positive against 57% of RTMP Broadcaster's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on November 3, 2026 and October 30, 2026 respectively.
