Widgets, weather, wind!

WIDGETS
Put tonight on your home and lock screens. Tonight's Weather mirrors the in-app strip hour by hour; Tonight's Verdict gives the one-glance clear / mixed / cloudy call. Each can follow a specific site, and a tap opens Sky to that night.

SMARTER WEATHER
Every hour now blends six global weather models — Europe's ECMWF, NOAA's GFS, and the German, Canadian, and UK models among them — into one consensus that's steadier than any single model. When they disagree, the strip flags the hour with a small "?".

WIND
Hours with gear-threatening wind get a green glyph on the strip and can trigger a "Windy tonight" alert.

YOUR LIMITS
Set your own precipitation, wind, and cloud thresholds so the strip and alerts match what you'll actually shoot in.

PLAN IN LOCAL TIME
Show every time — the weather strip, rise/set shading, and an object's rise/set/transit — in your device's clock or the site's local clock. Switch anytime in Settings › Times.

A LIVE "NOW"
A thin marker tracks the current time across the strip, with a soft glow at sunset and sunrise.

FIXES
• Interstellar comets like 3I/ATLAS now follow their real hyperbolic path — position, distance, and brightness are accurate again.
• Changing the Darkness setting repaints the chart instantly.
• After midnight, "Tonight" stays on the night in progress.

Clear skies!

### 1.4 — 2026-05-22

- Easy horizon creation with AstroPup Horizon
- Sites sync via iCloud

### 1.3 — 2026-05-15

- New name! "AstroPup Sky" is a more apt app name.
- Notifications when your viewing site has clear skies. Once per day, and preserving your privacy.

### 1.2 — 2026-05-04

- Bottom toolbar redesign: shading, filter, FOV, and "more" buttons
  on the leading edge with text descriptors below each glyph.
- Improved "Object List" lists every visible-tonight target with a
  per-row visibility timeline showing when each one is above the
  horizon.  Sort by hours visible, size, brightness, or name.
- Settings → Chart consolidates appearance options: opacity, color
  scheme, grid centre (Celestial pole / Zenith / Off), and a new
  "Darkness" picker (Sunset → Sunrise / Civil / Nautical /
  Astronomical).
- Bug fixes: chart no longer drifts upward on cold launch; "always
  visible" cells now match the "rises before sunset" color for a
  unified palette.
