A low-blue bedside clock under faint stars and tonight's real moon.
Night Sky is a clock for the bedside. The time sits large against a dark, warm sky where faint stars twinkle, and the moon in the corner shows tonight's actual phase and how much of it is lit. The digits glow in amber, red or soft moonlight, colours with little blue in them, at one of three brightness levels.
If you have an alarm set, it does the sleep maths for you: fall asleep in the next fifteen minutes and it tells you how long you will sleep, about how many 90-minute cycles that is, and when to be in bed to wake at the end of one. When all you want is the time, it can show the clock alone.
