ReceptionRating · Positive reviews · Number of ratings

Sub holds the better App Store score, 4.4 against 3.7. That said, the two scores are not equally well evidenced: Sub has 778 ratings behind it against 9, so its average is the more settled of the two. Written reviews complicate that: 15% of Sub's written reviews are positive against 20% of Time Zone Shifter's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Sub ships an update every 5 weeks, Time Zone Shifter monthly. The most recent releases landed on October 20, 2026 and October 13, 2026 respectively.
