A cinematic sky that follows the sun.
Astro paints the current hour in light — deep amber at night, warm gold at dawn, pale cream at noon. No icons. No clutter. Just the sky, told in colour.
Every detail is calculated from real solar data for your exact location — then dissolved into a single, continuous gradient.
A 17-stop palette shifts continuously across the 24-hour cycle, interpolated in real time. The colour is the clock.
The sun rides an elliptical arc plotted from your real sunrise and sunset times — left at dawn, right at dusk.
Know the next warm-light window and the next civil-twilight blue hour, drawn straight from solar geometry.
Drag to preview any moment of the day and watch the whole sky transform. Tap Live to snap back to now.
Four layered landscape planes drift at different depths as you tilt the device — a quiet sense of dimension.
Live sunrise, sunset, solar noon and twilight, fetched for your coordinates. Accurate, every single day.
Hover to linger on an hour. Between any two stops, all six colour channels are blended in real time.
Astro turns the passage of the day into something you can feel. Portrait-only, distraction-free, quietly alive.
