Vesper Sky

Read full description

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. PRICING & TRIAL Vesper Sky is a paid app with a 3-day free trial. After trial: • Monthly — $2.99/mo • Annual — $24.99/yr (saves 30%) • Lifetime — $59.99 (one-time, no subscription) Cancel any time in iOS Settings → Apple ID → Subscriptions. PRIVACY Vesper Sky does not sell your data. Photos stay on your device. Journal entries stay on your device. Anonymous location is sent to weather providers only to return weather for where you are.
