Questions
What are tabata intervals?
Tabata is 8 rounds of 20 seconds of all-out work and 10 seconds of rest, 4 minutes in total. Choose the Tabata preset to set it up.
Can I add a warm-up?
Yes. Set a warm-up in seconds and it runs once before the first work interval. Set it to 0 to skip it.
Will I hear the switch with my phone in my pocket?
Keep the screen on and the page open. Timer Owl asks the phone to stay awake while the timer runs, but some phones still pause web audio when the screen locks.
