FAQ
What does the timer do?
The script counts down exactly 60 seconds, displays remaining time, and fires an audible bell at zero (ISO 8601:2019).
Can I set a different duration?
Edit the JavaScript line timeLeft = X. For example, 90 gives a 1 min 30 s interval.
Why use a 1-minute timer for exercise?
One-minute high-intensity bouts improve VO₂ max as effectively as longer sessions (Gillen, 2016).
How loud is the alarm?
The file peaks at −1 dBFS, roughly 85 dB through laptop speakers—safe for short exposure (NIOSH, 1998).
Does the alarm work on mobile?
Yes, but iOS mutes autoplay until you tap the page, so test sound first (Apple Developer, 2022).
Why does the display flash red?
The last 10 seconds pulse to draw your gaze, echoing NASA’s “critical-phase” visual cueing (Human Factors, 2019).
Is the code open source?
You may copy or adapt the script; it contains no proprietary libraries.
How can microbreaks help focus?
“Short, regular pauses cut mental fatigue and sustain accuracy” (Kim et al., 2017).
