About Best Countdown

Best Countdown is a free browser-based countdown timer for anyone who needs to track a set amount of time. It suits people running focus sessions, cooking, working out, presenting or managing any timed activity, and it needs no installation or account.

Users can type a duration such as 5m or 25m, pick from quick presets ranging from seconds to hours, or choose a specific end time with a time picker. Optional tick sounds and gentle end alerts can be selected, and the large numbers can be shown fullscreen so the timer is readable from across the room. Timers can also be shared through a link so others see the same countdown.

The site adapts to phones, tablets and desktops, and it remembers sound and other settings between visits. It also includes a timestamp converter and a sleep calculator built around 90-minute sleep cycles.
