Boiling an egg, timing a presentation, or starting your next Pomodoro – Disco Timer is a universal countdown clock for all sorts of tasks. Setting the timer duration is based on 60-minute circle of traditional analog watches – you just wind it up with a single rotary gesture. Then tap the display to run, pause, or reset the timer. Large, high-contrast representation of the remaining time makes it glanceable from quite a distance. And an option to disable the Auto-Lock can keep the device awake while the timer is running.
