# Time vs RosterSync

The clearest difference is rating: RosterSync at 5.0 against Time's 3.0. Time's advantage is in-app purchases (none vs 1) and ads (none vs shown). On price, ratings volume, update cadence and device support there is nothing between them.

Both are free to download. RosterSync sells 1 one-off in-app purchase. Time asks for nothing beyond the download.

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.

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.
