Nowcast, daily view, rich styles, and unmatched attention to detail.

New: Lock screen widgets and Apple Watch Ultra support!

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

Who is Weathergraph for?

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 of 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.

Hourly forecast is updated every hour, 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.
Nowcast and alerts are powered by Foreca and depend on the precision of rain radars in your area.

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!

What’s New

Version 1.0.122

You can now disable the Nowcast on Watch complication or phone widgets, if you prefer to only see it inside the app. Head to the Nowcast preferences for the switch.

Fixed: Iconic lock screen widget now allows you to pick a custom zoom level. Tap the widget in the edit mode to set how many hours or days you want to see. Please re-add (remove and add again) the iconic widget, otherwise, it won't be able to update the forecast.

- Wind direction now shows up as an arrow in details (below the chart) and tooltip (long press the chart). A double arrow will appear for wind gusts.
- Wind gust strength now shows up in details and tooltip.
- Fixed the bug with abnormal storage space usage - my apologies!

Iconic: An additional lock screen widget with a simple icon style, to keep the lockscreen readable and easy on the eyes.

Lock screen widgets! Ready for iOS 16 and Apple Watch Ultra.
- Two large widgets: A signature weather graph and a text weather summary.
- Inline widgets to tell you current conditions, wind speed, and direction, precipitation or time of the next rain, or UV index.
- Many 1x1 widgets for individual weather metrics.
All of that is available for iOS 16, plus a lot of bug fixes for everyone.
Oh, and Apple Watch Ultra support.

Apple's new Apple Weather service. Be the first to try the hourly forecast from Apple's new weather service. Hit the Preferences button and switch the forecast source. Nowcast will be meanwhile provided by the good & trusty Foreca.

Custom cloud styles. You can now pick one out of four cloud styles: clouds plus precipitation icons, just clouds, lightweight cloud style, or no clouds (and more space for the temperature chart).
Thank you for the suggestions, Ian and Joe!

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!

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 matches your wallpaper better? Now you can - check 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.

You can now pick a location name as a complication title to see your whereabouts on the watchface.
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!

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 the UV index chart, and will tell you about today's (or tomorrow's) UV index maximum in the 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 the Foreca forecast. Alternatively (also new), you can choose to see precipitation as an area chart instead of bars.

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.

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!
