20 Minute Timer
A twenty-minute countdown is ideal for power naps — sleep researchers suggest that 20 minutes of rest improves alertness without grogginess. It's also a popular duration for focused reading sessions, yoga flows, and the first or final segment of a longer study block. In cooking, 20 minutes covers baking cookies, simmering sauces to thicken, and steaming broccoli to the perfect tenderness. This ad-free 20-minute timer runs entirely in your browser with Web Audio alarm sounds — no downloads or extensions needed. It stays accurate even when minimised.
