ReceptionRating · Positive reviews · Number of ratings

GymNext Flex Timer holds the better App Store score, 4.8 against 3.6. That said, the two scores are not equally well evidenced: GymNext Flex Timer has 2.2K ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 72% of GymNext Flex Timer's written reviews are positive against 73% of PyramidTimer HIIT Intervals's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

GymNext Flex Timer ships an update every 2 weeks, PyramidTimer HIIT Intervals weekly. The most recent releases landed on November 9, 2026 and November 2, 2026 respectively.
