What a 90 second timer is good for

Short countdowns are the ones people reach for most often mid-task — a rest between sets, a hold position, a rinse, a speed round — where glancing at a clock breaks concentration. This timer runs in the page, counts down out loud with an alarm at zero, and needs no app or sign-up.
