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. This comes in very handy when keeping an eye on the progress is as important as the finishing time itself.
