Vesper Sky tells you whether tonight's sunset is worth stepping outside for, and only interrupts you when it is. Every evening Vesper scores the coming sunset from 0 to 100, from cloud cover and cloud height, humidity, visibility and air quality. On great evenings you get one heads-up 45 to 60 minutes before sunset. Every morning at 7 you get the day in a sentence, even if you never open the app. WHAT'S INSIDE • Tonight's sunset, scored 0–100, with when to step outside. Rate the sky you saw and Vesper grades its own call over time • Sunset worth seeing: a heads-up sent only on great evenings • A 7 AM briefing with the day's weather in one line • Severe-weather warnings for your area (US, from the National Weather Service), even when the app is closed, plus a heads-up before rain starts • Falling pressure: an optional warning 12 hours before air pressure drops sharply, for anyone whose headaches follow the barometer • Live radar on a dark map, with a plain-language card about what the sky is doing right now • What to Wear: AI-written outfit notes for the day's feels-like temperature, humidity and wind, for a woman, a man and a child • Home Screen widgets in 7 kinds, a sunset countdown Live Activity on the Lock Screen and Dynamic Island, and an Apple Watch app with sunset complications • Made for iPhone Duo: two columns on the inner display, and a reading column beside the instruments when you hold it tall SIGNATURE FEATURES — Sunset Verify: rate the sky you actually saw. Vesper 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), each outfit chosen for the day's feels-like temperature, humidity and wind. — Journal: every sunset you rated, every outfit you built, every sky that meant something, saved to your device and never uploaded. DESIGN PHILOSOPHY Vesper is built like an instrument, not an ad-supported utility. White telemetry with Solar Gold and Frosted Indigo where intensity matters, a Deep Navy map, Sofia Pro for reading and Futura for display. Weather, worth reading. PRICING & TRIAL Vesper is a paid app with a 3-day free trial. After the 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 does not sell your data. Photos and journal entries stay on your device. Location is sent to weather providers only to return your forecast and is not stored, with two exceptions that keep a location rounded to about a kilometer so a notification can reach you while the app is closed: severe weather alerts, with your National Weather Service zone and county, and the 7 AM morning briefing and good-sunset alerts, with your time zone and an anonymous subscription ID the server uses to check that your subscription is active. Switch either off in Vesper and its data is deleted. Full privacy policy: vespersky.ai/privacy Terms: vespersky.ai/terms Privacy: vespersky.ai/privacy Support: brief@vespersky.ai
