ReceptionRating · Positive reviews · Number of ratings

快歌 holds the better App Store score, 4.7 against 3.0. That said, the two scores are not equally well evidenced: 快歌 has 55 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 70% of 快歌's written reviews are positive against 100% of Lyric Replacer's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

快歌 ships an update every 10 days, Lyric Replacer every 9 days. The most recent releases landed on November 11, 2026 and November 5, 2026 respectively.
