Weather,told straight.

Nimbus draws the sky you are actually standing under — sun above a horizon, ground below it — and puts the forecast on the ground where you can read it.

SCROLL — THE SUN FOLLOWS

The idea

Sun above.Ground below.Numbers whereyou read them.

Every other weather app is a table with a photograph behind it. Nimbus is a horizon. Light lives above the rule, data lives below it, and nothing ever competes for the same pixel.

Dawn, before the sun clears the rule.

The glow arrives first. Nimbus renders the light bleeding over the horizon eighteen minutes before the disc appears — which is exactly the window you care about if you are deciding whether to go out.

iPhone · 12:12

Day, with the whole sky open.

High sun, deep blue, the ground gone dark beneath it. Temperature sits at the top of the sky band where there is nothing behind it, and the forecast stacks below the rule.

iPhone · 19:34

Dusk, counted down to the minute.

Sunset is not a time in a list, it is the scene changing colour around you. The disc is on the rule, the glow is at its widest, and the card tells you how long the good light lasts.

iPhone · 23:48

Night, with the real moon.

Not a crescent sticker — a lit sphere with a projected terminator and craters that ghost through it. Tonight's phase is tonight's phase, drawn from where you are standing.

Apple Watch

Bigger, because you have one second.

The watch is not a smaller phone. Every step of type, every radius and every surface goes up — a glance target read at arm's length, often in sunlight, often in motion. Only the gutter shrinks.

  • The same stat components as iOS — value, unit and gradient bar, two up, on the identical ramps.
  • A horizon when there is a disc, a surface ramp when there isn't — clear states draw the full scene; rain and overcast let the screen's own colour carry the state instead.
  • Rain and wind alerts delivered before you leave, not after you're wet.

iPad

Room for the whole sky.

On iPad the scene stretches edge to edge and your saved cities live in a permanent sidebar, so switching between them is one tap and the forecast itself stays one unbroken column. Nothing is hidden behind a tab.

The system underneath

Every sky Nimbus can drawis an authored state.

Not a filter over a photograph. Each one carries its own sky ramp, ground ramp, horizon alpha, glow colour and disc presence — and the app only ever renders one of them.

0

Authored sky states — six times of day, four overcast, eight conditions.

0

Anchors on the temperature scale, from −60° to +50°.

0

Design tokens shared by the app, the widgets and this page.

All eighteen

Dawn through storm, day and night.

Temperature scale

Eleven anchors from −60° to +50°, diverging by hue rather than lightness, so a reading stays legible at a glance on any of those eighteen skies.

Real sun and moon

A lit sphere, not a sticker: true phase, a projected terminator, craters that ghost through it.

Minute nowcast

Rain starting in eleven minutes, ending in forty. Radar resolved to where you are standing.

Widgets everywhere

Lock Screen, Home Screen, StandBy, Dynamic Island and Live Activities — one scene, every size.

Golden hour timing

Sunrise, sunset, blue hour and civil twilight to the minute, with alerts before the light turns.

Unlimited favourites

Every place you care about in one strip, each carrying its own live sky.

No ads, no tracking
