Question 1

What is an interval timer used for?

Accepted Answer

An interval timer alternates timed phases — typically work and rest — and is used for HIIT, Tabata, circuit training, EMOM (every minute on the minute), AMRAP (as many rounds as possible) and stretching routines. It frees you from watching a clock so you can focus on effort.

Question 2

Can I create multiple different intervals in one workout?

Accepted Answer

Yes. Add as many interval rows as you want, each with its own label, duration and type (work or rest). The timer runs through all of them, then repeats the whole set for the number of rounds you choose.

Question 3

How are HIIT and EMOM different?

Accepted Answer

HIIT uses short intense work bursts followed by rest (for example 40s work / 20s rest). EMOM (Every Minute On the Minute) gives you exactly 60 seconds to finish a fixed amount of work — whatever time is left becomes rest before the next minute starts.

Question 4

Does the interval timer keep running if my screen sleeps?

Accepted Answer

The timer keeps counting while the tab is open. Wake-lock and screen-keep-alive depend on your device settings. For long sessions, keep the tab visible or pinned, and disable auto-screen-lock on your phone.
