Today, anywhere
Tap a point — a cabin, a terrace, a plot for sale — and get today's true sun window with the horizon that causes it. No account, no meter.
The difference
Terrain, not tables
A sunrise table says the day is 12 h 51 min. Behind a valley wall the sun arrives four hours late. Sundrift measures the wall.
The engine
One horizon, every date
The server reads the 360° horizon once; your device intersects it with the sun's path for any day of the year, instantly and offline.
Honesty
Labelled, always
Every answer states what was modelled — terrain resolution, buildings, vegetation — and what was not. The labels explained.
Three places, three truths
Computed live by the engine from elevation data alone — including the two facts Rjukan built a mirror and Norway's first cable car to cope with.
