Dorray holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: HIIT timer chronometer gym has 37 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 53% of HIIT timer chronometer gym's written reviews are positive against 50% of Dorray's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

HIIT timer chronometer gym ships an update every 7 months, Dorray every 6 weeks. The most recent releases landed on October 18, 2026 and October 1, 2026 respectively.
