Built to be read from across a room
In fullscreen the digits are sized from the screen's width and height, so the time takes up most of the display whether it is a landscape monitor or a tablet held upright. Digits are the same width as each other, so the clock does not wobble as the numbers change.
Candle (about 1900K) and Warm (about 2700K) put amber digits on near-black, which is easy on the eyes in the evening.
Candle (about 1900K) and Warm (about 2700K) put amber digits on near-black, which is easy on the eyes in the evening. Neutral (about 4000K) and Daylight (about 6500K) move toward white and blue-white. Paper reverses it with dark ink on a warm cream page, which reads best in a bright room. The Kelvin figures are approximate matches to the lamp colour, not measurements of your display.
Good uses for a clock that fills the screen
A second monitor on a desk, a stage or classroom display, a kitchen tablet, a streaming setup where you want the time visible, or a TV during a party. Pair it with the timer page for a countdown next to it, or the night clock if the room will be dark.
