Most interval timer apps force you into simple 30-second/10-second patterns. But what if you need complex sequences with grouped repetitions, breathwork patterns, or pyramid training? That’s where HIIT Timer – Interval Flex comes in – the interval timer designed for users who need more than basic patterns.
What is Interval Flex?
HIIT Timer – Interval Flex is a cutting-edge iOS app that solves the problem basic interval timers can’t: creating complex sequences like HIIT workouts with grouped intervals, breathwork patterns like 4-7-8 breathing, and pyramid training routines. Whether you’re doing advanced interval training, meditation breathing exercises, or any other complex time-based routine, Interval Flex handles the patterns that simple apps can’t.
