I built Weathergraph to be the weather app I always wanted — clear visual forecasts, professional-grade data, and zero tracking. WHY OUTDOOR ENTHUSIASTS LOVE WEATHERGRAPH • Up to 7 days of hour-by-hour weather in one glanceable chart • Know exactly when rain starts: “Light rain 2:30–3:15 PM,” powered by Rainbow.ai radar + ML • Rain alerts up to 60 min ahead — plan your run, hike, or ride with confidence • Built for kite surfers and sailors: wind speed + gusts, direction, pressure trends, UV peaks, heat index • Works offline — forecast cached for 24 hours, even in the mountains or on travels • Privacy-first — no accounts, no ads, no tracking, no data sharing SEE YOUR WEATHER AT A GLANCE Weathergraph turns raw weather numbers into a visual narrative: • Temperature as a smooth gradient line — spot the warmest hour for your bike ride • Rain & snow as blue bars — taller bars = heavier precipitation • Sunshine breaks as real sun-rays between clouds — find the best window to head out • Wind with gusts and direction arrows • UV index curve — know when to apply sunscreen (hint: above 3) • Barometer trends to understand pressure-driven changes • Today’s highs and lows, sunrise, sunset and twilight, right in the chart YOUR PLACES, ALL IN ONE APP Save home, the mountains, your next trip — any place you care about. Switch between them with one tap for the full 7-day detailed forecast, with your choice of weather source. A WEATHER STATION, WHEREVER YOU ARE Turn your iPhone or iPad sideways, and Weathergraph spreads into two columns: today’s details on one side, the charts on the other. A complete weather station in your pocket. Unfold an iPhone Duo, and it fills the big screen. APPLE WATCH APP DONE RIGHT • The only weather app with full hourly graphs on your watch face • Rich complications for every weather metric you care about WIDGETS THAT ACTUALLY HELP • Large widget with the nowcast, hourly charts, and up to a week of weather • Quick-glance widgets: UV with sunscreen reminder, wind with direction arrow, dew point & comfort scale, sunrise & sunset … • Lock screen widgets — see the detailed forecast before you even unlock • Stack several for your morning weather briefing TRUSTED DATA SOURCES Apple Weather · Rainbow.ai (world-class radar + ML nowcast) · Foreca · Open-Meteo (and its many national forecast models) · Pirate Weather (NOAA’s HRRR, GFS and GEFS) · yr.no Pilots and surfers check the wind, photographers plan golden hour, stargazers wait for clear skies.
