About the One Line Clock

One Line draws every digit as one continuous stroke of neon with round ends and a soft glow: pink for the hours and minutes, aqua for the seconds, on near-black. Just before a digit changes it erases itself along its line, and the new one draws itself in from the start, as if written in one movement of a pen.

The colons are pairs of small dots. It reads 12-hour or 24-hour time, every stroke stands whole when your device asks for reduced motion, and it fills the whole screen in its own colours. It is one of the fifteen digital faces of Clock with Seconds.
