Daily UI 014

Task was to design a countdown timer.
.
Idea:
This app can be used while running. The timer starts/pauses by tapping on the watch face, can reset when the timer is paused. We can also show the no.of steps, average heart beat rate etc(these things are not included just sharing the possibilities) when timer is stopped.

Why black background?
Because of OLED display screen we can save battery life(as much as we can) by using blacks.
.
Do share your thoughts on this idea.
