ReceptionRating · Positive reviews · Number of ratings

Volume Master holds the better App Store score, 4.2 against 4.0. That said, the two scores are not equally well evidenced: Volume Master has 201 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 54% of Volume Master's written reviews are positive against 67% of KB Volume Lock & Limiter's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Volume Master ships an update every 2 months, KB Volume Lock & Limiter every 3 weeks. The most recent releases landed on September 23, 2026 and September 9, 2026 respectively.
