ReceptionRating · Positive reviews · Number of ratings

FRF21TT holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Volume Booster has 7 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 94% of FRF21TT's written reviews are positive against 100% of Volume Booster's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

FRF21TT ships an update every 4 months, Volume Booster every 5 months. The most recent releases landed on October 14, 2026 and October 31, 2026 respectively.
