ReceptionRating · Positive reviews · Number of ratings

Core Advantage Interval Timer holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Best Interval Timer has 81 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 89% of Best Interval Timer's written reviews are positive against 50% of Core Advantage Interval Timer's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Best Interval Timer ships an update every 12 months, Core Advantage Interval Timer every 2 months. The most recent releases landed on October 11, 2026 and October 6, 2026 respectively.
