FAC Chorus's advantage is review sentiment (95% vs 83%) and ratings volume (61 vs 8). On update cadence, ads, device support and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

VividShaper holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: FAC Chorus has 61 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 95% of FAC Chorus's written reviews are positive against 83% of VividShaper's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

FAC Chorus ships an update every 5 months, VividShaper every 4 months. The most recent releases landed on September 22, 2026 and September 19, 2026 respectively.
