About this app

A black hole at the centre of your wrist, with the whole day around it.

In the middle of a deep star field, a black hole bends the light around it.
Its glowing orange disk turns without stopping, the bright arc wraps over
the top of the dark centre and a thin ring of light closes underneath, the
way light really bends around a black hole. The animation was modelled and
rendered in 3D, then looped so it never jumps.

Around it sits everything you check through the day. Across the top, the
temperature now and a weather forecast for the next six hours. Steps on the
left, heart rate and the UV index on the right, battery with a bar that
turns red below 15%. Below the centre, an LCD window shows the time in
white segments, with the weekday and the date in their own windows at nine
and three. Twelve colour themes change the numerals, icons and readings
together, and the seconds hand comes in red or silver.
