ReceptionRating · Positive reviews · Number of ratings

Caffeine Tracker holds the better App Store score, 4.9 against 4.5. That said, the two scores are not equally well evidenced: Caffeine Tracker has 40 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 79% of Caffeine Tracker's written reviews are positive against 100% of Shift's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Caffeine Tracker ships an update every 6 days, Shift every 3 days. The most recent releases landed on October 30, 2026 and October 24, 2026 respectively.
