Aurora

Free during development period. Aurora is a landscape, not a layout. Three curtains of light hang above a horizon, each one a real band with a bright crest and a long fading skirt, drifting slowly through the night. Nothing is a stored image; every ribbon is drawn. Below them the ground keeps only what it needs: frost glints scattered across the dark, and one far ridge sitting low on the dial. Above them a moon crosses the sky by the hour and shows the phase the sky is actually showing tonight. That moon is the one thing on the dial carrying data with no readout at all: where it sits is the hour, and the face it turns is the date. You read it the way you would read the sky. The time sits across the horizon and is lit by the sky behind it, the digits taking the curtain's own colours from its bright crest down to its base. Put the clock where it reads best for you and at the size you want it. Four readouts arrange themselves around the time. When there is room beside the clock, two of them go there and the other two sit below; when there is not, they fall into one row or two. You never choose the arrangement and it is never wrong. A fifth space in the middle draws a sparkline for anything with history behind it. Health and fitness: Heart rate, Resting HR, HR Zone, Body Battery, Stress, Sleep Score, Respiration, SpO2. Training: Recovery Time, VO2 Max (run), VO2 Max (bike), Active minutes, Weekly Intensity, Race 5K, Race 10K, Race Half, Race Marathon. Also: Steps, Floors, Distance, Total Calories, Active Calories, Elevation, Ascent, Descent, Notifications, Battery. Weather: Temperature, Feels Like, Humidity, Dew Point, Precipitation, Wind, Pressure, UV Index, Solar Intensity, Sunrise, Sunset. Each readout takes a colour you pick, or follows the sky along with everything else. Your battery sits at the foot of the dial as a short curtain of its own, lit as far as the charge reaches. It shades from the drape's base colour toward its crest as it empties. A plain battery icon is one tap away if you would rather have one. Fourteen skies to choose from, or set the two colours yourself and watch the curtains, the clock and the readouts all follow. A time-of-day tint breathes through whichever you pick, warming at dawn and deepening toward midnight. Burn-in-safe always-on display carries the same sky in outline. The same three curtains at the same places, traced instead of filled, the same moon on the same arc, and the clock keeping the same graded colour. Everything is drawn at one brightness, and the whole screen sits well inside the always-on budget. Choose its size, its scene, and whether it carries the date, the battery, both or neither. Made for AMOLED, where black is simply off.
