Vesper Sky
The instrument for the sky
Free · In-App Purchases · Designed for iPad. Not verified for macOS.
Vesper Sky is an editorial weather app. Where other apps give you a grid of numbers, Vesper Sky gives you a sentence about the sky — the kind a thoughtful friend would write if they'd just stepped outside.
It isn't for the storm chaser or the pilot. It's for the person who opens a weather app three times before noon and wants the one line that tells them whether the jacket was the right choice.
VESPER SKY INSTRUMENT CALIBRATION
• Proprietary ML sunset forecasting — built on years of observed sky data, the model grades its own predictions and tracks accuracy over time
• Atmospheric inputs — cloud cover, humidity, pressure, and sun position fed through a premium scoring pipeline
• Editorial wardrobe & style briefs — AI-generated fiber notes (merino, linen, boucle) written for the day's actual conditions, not generic temperature bands
• Dynamic Island + Live Activities for sunset countdown
• Home Screen widgets — 7 kinds, all sizes
• Apple Watch app with sunset complications
SIGNATURE FEATURES
— Sunset Verify: rate the sky you actually saw. Vesper Sky scores itself against your rating and builds your verification history over time.
— The Sky tab: live radar overlaid on a custom dark map, with an editorial card that tells you in plain language what the atmosphere is doing right now — not just in numbers.
— What to Wear: three silhouettes (woman, man, child) with biometric-accurate outfit recommendations, each fabric chosen for the day's precise feels-like temperature, humidity, and wind.
— Journal: every sunset you rated, every outfit you built, every sky that meant something — saved to your device, never uploaded.
DESIGN PHILOSOPHY
Vesper Sky is built like an instrument, not an ad-supported utility. The color system is monochrome: pure white telemetry with Solar Gold and Frosted Indigo accents where intensity matters. The map is Deep Navy Clay. The typography is Sofia Pro for body, futura-pt for display. Every surface earns the word "premium."
Weather, worth reading.

Ratings & Reviews
- This app has not received enough ratings or reviews to display an overview.
Severe weather, even when the app is closed.
• National Weather Service warnings for your area now arrive as notifications, not only when you open Vesper.
• Warnings are sent as Time Sensitive, so they can break through a Focus when you allow it.
• Tapping a warning opens it.
• The alert banner names the county you're actually in, not whichever one the forecast office listed first.
• Advisories you clear collapse to a single line instead of vanishing, and one tap brings them back.
Requires iOS 16.4 or later.
