App: Weathergraph weather widget
Developer: Tomas Kafka
Genres: Weather, Sports

Newly added: A new WatchOS 10 app with Smart Stack widgets, native mac app, rain & snow alerts and vertical (in a Dark Sky app style) layout option.

Weathergraph is a beautiful visual hourly weather widget and forecast for Watch, iPhone, iPad, and Mac, with the Apple Watch app, watchface complications and weather alerts.
Powered by Apple Weather, Foreca, Pirate Weather (aggregating NOAA's HRRR, GFS and GEFS), Open-Meteo, and yr.no/met.no.

It shows:
- Nowcast (real-time rain & snow forecast updated every 30 minutes – PRO only)
- Rain & snow alerts based on nowcast data (PRO)
- Hour-by-hour temperature (main colorful line)
- Hour-by-hour precipitation — rain, and snow (blue chart)
- Hour-by-hour cloudiness (cloud cover) and sunshine (clouds on top + sun rays)
- Hour-by-hour wind speed (red line) and direction (red arrows)
- Hour-by-hour precipitation or dew point (dotted line)
- Hour-by-hour atmospheric pressure, absolute, or rate of change (purple line or arrows)
- Hour-by-hour UV index (rainbow dashes)
- Real day/night (sky color)
- Daily temperature minimum and maximum (overlaid above chart)
- Actual temperature and place (on the top)
- Sunrise and sunset times

Hikers, runners, bikers, kite surfers, pilots, and many outdoor enthusiasts around the world love the at-glance readability, customizability, and reliability.

Weathergraph is offline capable. The app caches the last acquired forecast for up to 24 hours, allowing you to hike or run outside the network (or go running or biking with a wifi-only Apple Watch) and still see the most recently fetched data. The data refreshes automatically once a connection is available.

The hourly forecast is updated every hour, nowcast and rain alerts update every 30 minutes. If rain or snow is expected during the next 3 hours, you will get a notice on a widget (iPhone, iPad & Mac), a large complication (Watch), and a detailed 3-hour precipitation chart in the app.
Nowcast and alerts are powered by Foreca and depend on the precision of rain radars in your area.

Weathegraph cares about your privacy. No ads, no tracking, and no sharing of locations with third parties. This is how I want all the apps on my phone & watch to behave.

You can unlock professional Apple Weather, Foreca, Open-Meteo, and Dark Sky forecast sources, weather alerts, nowcast, and all styles and options via a reasonably priced subscription, which covers the cost of data and allows me to further improve Weathergraph. One-time Weathergraph Forever unlock is also available.
Thank you for your support!

If you liked Dark Sky, Weather Line, Weathertron, or Weather Strip, then Weathergraph might be the best replacement :).

Release notes:
NEW:
- Nowcast title for snowy conditions matches the snow color (thanks, Sivaram!)

PREVIOUSLY:
- Preferences now have their own screen on the watch, just like in the iPhone app.
- Rain and snow icons under clouds are now colored.
- Tweaked the sky of the light themes.
- You can now tap the weekly chart to scroll directly to that time.
- Weekly chart: You can now see a week at a glance below the main chart, both in the app and in the large widget.
- Scroll the weekly chart to peek into the future even more (as long as the forecast provides more than a week of data). Long press the weekly chart to zoom to that time in the main chart.
- Sun glow: As the murky autumn arrives, know when to look forward to a healthy dose of sun rays. The warm glow above the cloud layer highlights particularly sunny times.
- Smoother scrolling through the app and charts, especially on the older devices.
- Option to have light drawn clouds with weather icons underneath.
- New METAR unit set for aviation fans.
- Full-screen chart now allows you to scroll through more than a week (if the forecast is long enough).
- Wind lock screen widget uses the arrow for wind direction and circled icon when gusty.
- Brand-new sunrise/sunset complication and lock screen widget, that shows the next sun event (or tells you that you are in a polar day/night zone if you are that lucky).

Vertical layout improvements:
- New zoom-in and zoom-out buttons.
- Both real and apparent temperature at once.
- Wind gusts now appear in the wind view next to wind speed and direction.

Revamped watchOS 10 app
- Weathergraph now shines on the watch with a sleek new look! Pin Weathergraph's widgets to watchOS 10s Smart Stack, just a twist of a crown away from the watchface.
- Note: Due to a location permissions issue on watchOS 10, the app may not update your location automatically. Don't worry — just open Weathergraph on your iPhone, and it will sync the location to your watch.

AND BEFORE:

Weathergraph is now also a native mac app for both Apple Silicon and Intel macs.

Beta of weather alerts arrives to Weathergraph – get a heads-up before rain or snow! I'm all ears for the feedback, thanks!

Arrrr! Pirate Weather arrives as a new data source, indie-made by the exceptional Alexander Rey. High resolution and accuracy over the continental US and Canada, using NOAA's HRRR, GFS and GEFS models. Comes with its own 60 minute nowcast.

The independently run Open-Meteo forecast source adds 14 days forecast and now comes with precipitation probability as well, matching other services. This update also adds 2 extra days to the Apple Weather source, improving it to 9 days in total.
