10 second timer

A ten second timer, running in your browser with a sound at the end. Ten seconds is the classic countdown: the last stretch before something starts, and the standard delay on a camera self-timer.

How it works

  1. Tap Start. The ring empties as the ten seconds run down.
  2. Use it as a countdown before you begin: the last ten seconds of a rest, or the run-up to a photo.
  3. A tone marks the end, so you can look away.
  4. Want it on your phone with a quick-start widget? Open the same timer in NanoTimer.

Frequently asked questions

What is a ten second timer used for?
Mostly as a run-up rather than a task: the countdown before a lift, a sprint or a recording starts. It is also the usual delay on a camera self-timer, which is long enough to press the button and get back in frame.
Is ten seconds long enough to rest?
Not really, and that is the point of the Tabata format, where the ten second gap between rounds is a breath rather than a recovery. If you want an actual rest between sets, thirty to ninety seconds is the usual range.
Can I start it hands-free?
In the app, yes. NanoTimer registers a timer shortcut, so you can start one from Siri, Spotlight or the Action Button without opening anything.
