Verdict

The call

ReceptionRating · Positive reviews · Number of ratings

RosterSync holds the better App Store score, 5.0 against 3.0. Both are backed by a comparable volume of ratings — 2 and 3 respectively. Written reviews complicate that: 100% of Time's written reviews are positive against 80% of RosterSync's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Time ships an update every 6 days, RosterSync every 3 days. The most recent releases landed on October 6, 2026 and October 12, 2026 respectively.
