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.

Cedar Weather turns the forecast into a decision. Most weather apps hand you a temperature and leave the rest to you. Cedar reads the same conditions and tells you what they are actually good for — a ride, a hike, a day at the beach, a walk through town, or an afternoon indoors with a coffee. WHAT IS TODAY GOOD FOR? The home screen shows live conditions where you are, then rates the day for the things you actually do — cycling, walking, hiking, the beach, a city walk, a cafe day, and skiing where there is snow. The scoring runs on your phone and weighs temperature, wind, the chance of rain and how much of it, UV and visibility together, so cycling weather and beach weather are judged on their own terms. A still, overcast 18 degrees is a fine riding day and a poor beach day, and Cedar says so instead of leaving you to work it out from a row of icons. WATCH THE RAIN MOVE Open the weather map for animated rain radar with a time scrubber, so you can run a shower forward and see whether it clears before you leave. Cloud cover and temperature layers sit on the same map, and every region is coloured by how good conditions are right now. Filter the map to cycling, hiking or the beach and the whole picture recolours for that one activity — useful when the question is not what the weather is, but where the good weather is. HOURLY FORECAST AND THE WEEK AHEAD An hour-by-hour view with rain chance, wind and temperature shows you the window that matters. Tap any day in the 7-day forecast to open its own hourly strip, or tap any region on the map for a full activity breakdown and chart. When a front is moving through, the hourly forecast is the difference between getting caught and getting home dry. PLAN THE WEEKEND Cedar ranks the regions around you by how the weekend weather is shaping up, so choosing where to go is a glance rather than ten browser tabs. Weather for hiking in the hills while the coast sits under cloud, or the other way round — you can see it on one screen. Detailed regional breakdowns run across more than 200 countries, and worldwide city search reaches anywhere else: look up Denver, Seattle, Zurich, London or wherever you are heading and get a 7-day forecast before you commit to the trip. HOME-SCREEN WIDGETS Illustrated weather widgets put current conditions and the day ahead on your home screen, drawn as a scene rather than a wall of digits. Glance at the phone, know the sky. WEATHER ALERTS THAT EARN THEIR PLACE A short morning briefing, a weekly outlook, and severe weather alerts when something is genuinely on the way. You choose which ones arrive and which stay off, and none of them shout for attention. BUILT ON MORE THAN ONE SOURCE Forecast data comes from Open-Meteo, with a second provider standing by as a fallback, so one bad response upstream does not quietly become a bad forecast on your screen. Coverage is near-global, the interface speaks 37 languages, and regions carry the names locals actually use for them. FREE, WITHOUT THE USUAL CATCH No ads. No subscription. No in-app purchases. No account needed to see the forecast, and no tracking. Cedar Weather is made by one developer in Switzerland under the name Florignite, and it stays free and ad-free because it is not selling you or your data to anyone. It began with a small Saturday-morning question — is it worth taking the bike out? — and the answer was never in the temperature alone. If you cycle, hike, walk, chase clear skies at the weekend, or simply want an honest hourly forecast and a rain radar that loads quickly, Cedar Weather was built for you.
