Verdict

The call

The clearest difference is review sentiment: Murmur at 55% against NDI HX Camera's 11%. Murmur also leads on update cadence (weekly vs every 5 months). NDI HX Camera's advantage is rating (4.4 vs 3.8) and ratings volume (530 vs 17). On price, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

NDI HX Camera holds the better App Store score, 4.4 against 3.8. That said, the two scores are not equally well evidenced: NDI HX Camera has 530 ratings behind it against 17, so its average is the more settled of the two. Written reviews complicate that: 55% of Murmur's written reviews are positive against 11% of NDI HX Camera's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Murmur ships an update weekly, NDI HX Camera every 5 months. The most recent releases landed on October 22, 2026 and October 30, 2026 respectively.
