Description
I built Weathergraph to be the weather app I always wanted — clear visual forecasts, professional-grade data, and zero tracking.
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 all metrics and your choice of weather source.
WHY OUTDOOR ENTHUSIASTS LOVE WEATHERGRAPH
• Up to 7 days of hour-by-hour data in a single glanceable chart — temperature curves, rain bars, wind, clouds, sunshine ... all in one timeline
• Widgets with real graphs for Apple Watch, iPhone, iPad, and Mac
• Know exactly when rain starts: “Light rain 2:30–3:15 PM,” powered by Rainbow.ai radar + ML. Perfect for runners, cyclists or ski trips.
• Rain alerts up to 60 min ahead. Plan your workout, hike, or fishing trip with confidence.
• Built for kite surfing and sailing enthusiasts: wind speed + gusts, direction, pressure trends, UV peaks, heat index
• Works offline — your forecast stays cached for 24h, and keeps working even in mountains or travels
• Privacy-first design — 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 — instantly spot the warmest hour for your bike ride
• Rain & snow as blue bars — taller bars = heavier precipitation
• Sunshine breaks shown with actual sun-rays between clouds, highlighting the best time for outdoor activities
• Wind visualization with gusts and direction arrows
• UV index graph — know when to apply sunscreen (hint: above 3)
• Barometer trends to understand pressure-driven changes
• Background color changes with the sky from dawn blue to sunset orange
• Today's highs and lows marked directly in the chart
• Sunrise/sunset times with twilight shading
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
• Caches your forecast for 24 hours — even when you’re offline on a mountain ridge
WIDGETS THAT ACTUALLY HELP
• Large widget shows nowcast and hourly charts plus up to week of weather
• Quick-glance widgets: UV index with sun protection reminder, wind speed with direction arrow, dew point and comfort scale, sunrise & sunset time ...
• Lock screen widgets to see the detailed forecast before you unlock
• Stack multiple widgets for your morning weather briefing
TRUSTED DATA SOURCES
Weathergraph pulls from a curated set of professional forecast systems:
• Apple Weather
• Rainbow.ai (world-class radar + ML nowcast)
• Foreca
• Open-Meteo (and its plethora of national forecast models)
• Pirate Weather (NOAA's HRRR, GFS and GEFS models)
• yr.no
Pilots and surfers check wind graphs before takeoff. Photographers plan golden hour. Skiers know when exactly the blizzard starts.
If you loved Dark Sky or Weather Line, you’ll feel right at home. Cleaner than Wunderground, easier than Windy or Windfinder.
Weathergraph is free to download and use. Open the app anytime and get beautiful, detailed forecasts from the world’s best weather models — all sources, no ads, no accounts. Upgrade to Pro to unlock widgets, Apple Watch complications, multiple saved locations, background rain alerts, and full customization. Pro comes with a 7-day free trial, then annual membership or a one-time lifetime purchase.

Across 10 languages, something may have slipped through. If you spot a translation that's off, email me a screenshot — thank you!
Previously:
Minute-by-minute rain, anywhere on Earth. Rainbow.ai's nowcast now covers the entire globe — including regions where radar was sparse or missing. Wherever you are, you get the same precise 4-hour forecast with minute-by-minute rain and snow detail.
- Truly global nowcast coverage, including Asia, Africa, South America, and the Arabian Peninsula
- Five geostationary satellites and hundreds of radars, 1 km² resolution
- Rain alerts now work everywhere in the world
And before that:
New "Next few hours" bar sits right below the summary and keeps the upcoming hours visible at all times. One quick glance tells you if rain is coming, when clouds will clear, or when the sun goes down.
And before that:
Multiple locations — the most-requested Weathergraph feature — is finally here. Save home, work, your favourite trails, or your next destination. Switch between them instantly with a single tap.
- Save multiple locations — home, work, mountains, your next destination

If you know friends or fellow outdoor lovers who would love Weathergraph's visual forecast, I'd be grateful if you could share or tweet a screenshot to let them know.
Thank you! Tomas.
