About this 15-minute timer
A one-click 15-minute countdown, most often used for a snack or stretch break, letting dough rest, or a focused reading sprint. It runs in your browser and rings when it reaches zero.
A quarter of an hour
Fifteen minutes is the standard short break in most workplaces and the length of a decent reading or revision sprint. In cooking it's the usual first check-in for baking, and the rest time most bread doughs want between folds. It's the shortest block that feels like real time rather than a snatched moment.

Tips for using a 15-minute timer
- Fifteen minutes of focused reading a day adds up to roughly 15-20 books a year at average reading speed.
- Most dough recipes call for a 15-minute bench rest so the gluten relaxes before shaping.
- For studying, 15 minutes is long enough to get into a topic without the fatigue that kills recall.
