Frequently asked questions
How do I create an interval timer?
Press New timer, name it, add a round for each interval with its length, set how many times to repeat the sequence, and save. The timer gets its own link straight away.
Can I use the timer without creating an account?
Yes. Timers built while signed out work exactly the same — they're just unlisted, so keep the link. An account collects them all on your profile and lets you edit them later.
How do I share a timer?
Every timer has a unique URL. Use the Copy button on the timer page and send it on — whoever opens it can run it without signing in.
Does it work on phones?
Yes. The layout adapts to any screen, and fullscreen mode keeps the display awake while a workout runs.
Is there a limit on how many timers I can create?
No limit.
How do I delete a timer?
Open the timer while signed in as its owner and use Delete, or delete it from the list on your profile.
