1 Hour Timer

One hour is a natural unit of measure for deep focus, long-form cooking, and structured activities. Use a 60-minute timer for extended study sessions, slow oven roasts, client meetings, and timed exam practice. Many productivity systems — including time-blocking and the 52/17 method — use one-hour windows as their primary planning unit. It's also the standard length for massage appointments, therapy sessions, and many online courses. This free 1-hour browser timer maintains accuracy through background-tab throttling using absolute time references. An alarm chime plays when your hour is up, even if your screen is off.
