ReceptionRating · Positive reviews · Number of ratings

Sphere Time holds the better App Store score, 4.2 against 4.0. That said, the two scores are not equally well evidenced: Sphere Time has 10 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 75% of Sphere Time's written reviews are positive against 100% of TimeZone Carousel's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Sphere Time ships an update every 5 weeks, TimeZone Carousel every 3 weeks. The most recent releases landed on September 9, 2026 and June 4, 2026 respectively.
