ReceptionRating · Positive reviews · Number of ratings

Rounds Timer for CrossFit holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: Interval Timer has 534 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 77% of Interval Timer's written reviews are positive against 50% of Rounds Timer for CrossFit's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Interval Timer ships an update every 4 weeks, Rounds Timer for CrossFit fortnightly. The most recent releases landed on October 16, 2026 and September 12, 2026 respectively.
