What is a 45 minute timer good for?

Forty-five minutes is the length of a classic school lesson — and a favourite deep-work block for people who find a full hour too long. One click starts it; the alarm ends it.

Frequently Asked Questions

Will my computer going to sleep stop the timer?

It can — for long countdowns keep the screen awake or adjust your sleep settings so the browser keeps running.

Can I add a few extra minutes?

Press Reset, tweak the minute field (for example to 50), and press Start again — the preset is just a starting point.
