ReceptionRating · Positive reviews · Number of ratings

Core Advantage Interval Timer holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Interval Timer has 3.5K ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 50% of Core Advantage Interval Timer's written reviews are positive against 67% of Interval Timer's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Core Advantage Interval Timer ships an update every 2 months, Interval Timer every 4 weeks. The most recent releases landed on August 17, 2026 and September 25, 2026 respectively.
