FAQs
Can I project this on a screen?
Yes. Fullscreen mode (F key) hides the UI for clean projection.
Can students see it on their devices?
Share the URL — it works on any device with a browser. No app install needed.
What can you actually do in one minute?
More than you think: brush your teeth, do 15 pushups, take 6 deep breaths, or skim a page. A one-minute timer is about focus, not duration.
How accurate is a one-minute countdown?
The timer counts milliseconds. For a one-minute count, it’s within a fraction of a second — accurate enough for any micro-task.
