- Next 24 hours — horizontal scroll strip with a temperature sparkline, hover for per-hour values
- 10-day daily list — high / low, precipitation %, condition icon
- Per-day detail modal — hourly temperature curve, hour-by-hour breakdown (feels-like, humidity, cloud cover, wind, precipitation), UV max, peak wind gust, sunshine duration, a sun arc with day length, a day-level AQI tile and any alerts overlapping that day
| European AQI · US AQI | Auto-routed by country |
|---|---|
| Pollutants | PM2.5 · PM10 · Ozone · NO₂ · SO₂ · CO · Dust |
| Pollen | Alder · Birch · Grass · Mugwort · Olive · Ragweed |
| Trends | 5-day hourly history in the expandable drawer |
| Dominant pollutant badge | Surfaced at a glance on the collapsed card |
A full-screen map with four swappable weather layers:
| 🌧️ Precipitation | Animated radar overlay — past 2 hours + 30-minute nowcast — with a timeline scrubber, play/pause and step controls |
| ☁️ Clouds | Gridded cloud cover painted as soft tinted blobs |
| 💨 Wind | Animated streamline particles flowing along the live wind field, colour-ramped by speed |
| 🌡️ Temperature | Bilinear-sampled heatmap with a smooth colour ramp |
Move your cursor over the map to see the value at that point. Every saved location appears as a labelled pin, with the active one highlighted by a pulsing halo.
- 🇺🇸 US coverage via
weather.gov - 🇪🇺 European coverage via MeteoAlarm national feeds
- Routed automatically by the active location's coordinates
- Top-of-dashboard banner, severity colour-coded
- Detail modal with full text, affected areas and timestamps in the location's timezone
- Alerts overlapping a selected day also surface in the per-day modal
Desktop notifications fire the first time a new alert is seen, with per-severity toggles (extreme · severe · moderate · minor) in Settings.
- Explicit sunrise & sunset times with the day-length total
- Daylight progress bar that animates to the elapsed share of the day
- Concrete golden-hour windows (not just a generic countdown)
- Moon-phase card with illumination percentage
🌙 Click the moon — detailed view
A fully SVG-rendered moon with:
- Selenographically-placed maria (Mare Tranquillitatis, Imbrium, Serenitatis, …)
- 23 named craters at their real coordinates (Tycho, Copernicus, Kepler, Aristarchus, …)
- Tycho's ray system painted across the southern highlands
- Regolith texture, terminator shadow line, limb darkening and faint earthshine on the unlit side
- Real-time libration wobble based on lunar age
- Apparent disc size scales with Earth–Moon distance (1.06× at perigee · 0.94× at apogee)
Plus, in the panel:
- Illumination % · lunar age (days) · Earth–Moon distance with a perigee/apogee orbit bar · angular diameter
- Moonrise · transit · moonset — in your location's timezone
- The next four principal phases with countdowns
- The current zodiac constellation the moon is passing through
Eight outdoor activities scored good · fair · poor with reason chips that explain why — too hot, windy, golden hour, slippery roads, ideal, etc.

Air quality is factored into outdoor activities: poor AQI downgrades the score and surfaces the air-quality band as the reason.
