Beautiful visual hour-by-hour weather forecast app with widgets and watch complications.
Nowcast, daily view, rich styles, and unmatched attention to detail.

Weathergraph is a beautiful visual hourly weather widget and forecast for Watch, iPhone, iPad, and Mac, with Apple Watch app and complications.
Powered by Dark Sky, Foreca, OpenMeteo, and

It shows:
- Nowcast (real-time rain & snow forecast updated every 15 minutes - PRO only)
- Rain & snow alerts based on nowcast data (PRO, watch-only so far, coming to iPhone and iPad)
- 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

Hourly forecast is updated every hour and cached offline — the chart always shows the current temperature according to the last obtained forecast, even when you go off for a long trek without a data connection.

Nowcast and rain alerts update every 15 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.

You can unlock professional 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. Thank you for your support!

Nowcast and alerts are powered by Foreca and depend on the precision of rain radars in your area.

If you liked Weather Line, Weathertron, or Weather Strip, you might like Weathergraph too :).

What’s New

Version 1.0.111

Apple's new Apple Weather service (beta). Be the first to try the hourly forecast from a beta version of Apple's own new weather service. Hit the Preferences button and switch the forecast source. Nowcast isn't available yet, so it will be provided by the good & trusty Foreca.

And dew point comfort scale. Enable humidity or dew point in the chart to see the feel for a given hour on a dew point comfort scale. From dry through pleasant, comfortable and humid up to miserable or extreme, Weathergraph will inform you both in the details section and chart tooltip. Thank you for introducing me to the comfort scale, Sebastian!

Plus fixed large widget layout on some text sizes on iPad.

Interactive chart, just in time for summer trips! Need to know the exact conditions for a given hour? Long press the chart to show all the data, or press and slide your finger over the chart to “scrub” through the forecast.

Custom style for widgets! Love the Iconic style, but the blue-accented one on a black background would match your wallpaper better? Now you can.
The new Widget style and background option is waiting for you in the preferences.

Accent styles are arriving to iPhone & iPad. Pick one of a large scale of accent colors to match your mood or wallpaper.
Weathergraph is now also significantly faster, thanks to chart rendering using the extra cores your iPhone, iPad or watch has.

Light, dark and black (for widgets) color scheme and wind gust chart.
Set light and dark mode as you like, for widgets and iPhone app.
You can now override the widgets to always use light, dark, or a new 100 % black mode, to better suit your wallpaper. And the same goes for the app. Prefer always light or dark? Pick it in preferences.

New option in Wind Style preferences allows you to plot wind gusts on a chart as a transparent area above the wind line in a same color as the wind.
This comes really handy when cycling or kiting, or just to not have a nice day ruined by strong wind gusts.
Made thanks to Mikael & many others, who suggested this feature - thank you!

Also, when a watch complication is set to Full chart, nowcast info will still show up when a rain is coming. And few cases when small complications have mistakenly shown No Data or wrong temperature have been fixed.
And fixed a few bugs with background updates.

You can now pick a location name as a complication title to see your whereabouts on the watchface.
A better time format in summaries for 24-hour time countries, and fixes for always-on mode for Apple Watch.
Nicer Always-on-display for Apple Watch complications.
Every style now has a custom-fit variant for always-on-display - enjoy the colorful watchface even with a wrist down.
Thank you, Josh, Case, and everyone else, for suggesting this improvement!

Looks gallery - pick one of preset chart looks for a quick start, then customize the chosen one as you need.
Brand new legend that explains everything, including the newly added metrics. Long overdue, thank you for your patience!

Keep it simple with the new iconic style, or add as many metrics into the chart as you like.
UV index: Weathergraph can now show UV index chart, and will tell you about today's (or tomorrow's) UV index maximum in details section. Green = low, yellow = moderate, red = high, and purple = very high.
And finally, a rain probability. You can now see both precipitation and precipitation probability with Foreca forecast. Alternatively (also new), you can choose to see precipitation as an area chart instead of bars.

Weathergraph now displays atmospheric pressure.
Pick one of the two visualizations:
- the line works great to see the absolute pressure development over time
- arrows clearly illustrate a rate of change

If you like the app, I would be thrilled if you could post a link or screenshot anywhere outdoor people like you hang out :).
Thank you! Tomas.

Coliseum Lipford ,

Can’t change the unit scales.

Just downloaded Weathergraph on my iPhone and watch and it seems to be nice since I’ve always liked graphs for data. But I can’t change the the units on the iPhone from Metric to Imperial (I live in the USA). There is an option on the watch and that works fine to change the units, but not on the iPhone app. Am I missing something or is this an oversight that needs to be added in an update? Being an option only in Pro just wouldn’t make sense, since it can be changed on the watch. There is no Settings menu for any changes. Thanks for listening.

Yes, I did find the Preference button. I apologize, somehow I completely overlooked that. It was late and I was tired, I guess.
So far the app looks good and the prompt response is appreciated. So I raised my review to four stars. I haven’t had the app but a couple days, so I’ll have to use it for a while before determining if it’ll be a five or not.
Thank you for your help!

Hello, there is a Preferences button right under the daily forecast, and in a next window you will find Units setting at the bottom - did you find it?

Brilliant weather app. Instant favorite and must-have for watch, phone, and iPad. App used to be watch-only, and I found it when I bought an Apple Watch and was looking for a weather app that quickly and visually shows key weather information. This app stands out from all the other options with its design and attention to both visual and functional detail. The graph itself raises the usefulness of an Apple Watch significantly—it works in so many ways to supplement other key at-a-glance daily information and also as the basis for a watch face that can be a whole miniature weather center. The graph, multiple complications for current conditions, wind and/or other options and RadarScope make for a most useful weather face. This app elevates the watch. Recently the developer has added phone and iPad apps. The graph looks stunning on both devices and as app and widget conveys weather information so very well. I have numerous weather apps and Weathergraph has instantly become one of my main widgets and first weather references on my devices. With multiple data sources and options for customizing, it shows all the key weather forecast and conditions most effectively. Again it is a brilliant combination of aesthetic and functional design. Just perfect.
Update: the developer keeps refining and adding great new features, refinements, and options, giving the app even more looks on all the platforms.

Wonderful watch weather app!

This is a truly great weather app for your watch. I began to use it because my other weather apps on the watch seemed to always be “updating” when I went to look at them, and weathergraph always had data. It might be 10 mins old, but on my watch that’s fine. If I want totally the most detailed forecast I’ll use one of my 6 favorite weather apps on my phone. Even when weathergraph is updating it still has data available to look at.

After a bit I began to appreciate the amount of useful data that is shown on the screen. I get temperature, wind, precipitation at a glance, for one day or five days. I also get cloud cover, something you don’t get easily even on phone apps. I also get sunrise and sunset. All instantly available. When using my watch I usually just want an overview of today or tomorrow, and I get far more than that with weathergraph. It has taken me a few weeks to really appreciate the quantity of information offered by weathergraph and get used to reading it at a glance.

I have several weather apps on my watch, and quite a few more on my phone, but I get more information more regularly from weathergraph than all of the others. This is a great app, and I’m so happy to have it!

Thank you! It was a pleasure to read your review :). Enjoy Weathergraph!
