Getting Started

How do I read the weather? #

Please have a look at the legend:

How to Read the Charts

Day/Night Sky and Sunshine:

Chart background shows a day/night cycle and sunshine — the brighter the background, the more sun.

Cloudiness:

The layer on top shows cloudiness (percent of the sky obscured by clouds).

Sun Glow:

Warm glow above the cloud layer highlights particularly sunny times.

Wind Speed and Direction:

The higher the chart, the higher the wind speed.
Arrows show wind direction, double arrows mean wind gusts.

Temperature:

The main colored chart shows temperature, real or feels like (as set up in preferences).The dashed line shows freezing point (0 °C or 32 °F).

Rain/Snow and Precipitation Probability:

The bar chart shows an amount of precipitation (blue = rain, white = snow), while the light blue area shows precipitation probability (0 — 100 %).

Humidity or Dew Point:

You can add a relative humidity (RH) or a dew point to the chart in form of the blue dotted line. This will also show the dew point comfort level in forecast details.
Humidity has a 0 — 100 % range, where 2/3 of chart height corresponds to 100 %. Dew point shares the range with the temperature chart.

How do I change complications on my Apple Watch watchface? #

Apple has made a great step-by-step guide to changing and customizing watchfaces.

Key Features

How do Nowcast and rain alerts work? #

With a Pro unlocked, Weathergraph checks nowcast every 15 minutes for upcoming precipitation in your location.

If rain, sleet, or snow will arrive in the next 2 hours according to nowcast radars, Weathergraph will show a warning on the complication.

Weathergraph also shows rain or snow probability, when there is no precipitation detected yet, but the nowcast reports a higher than 50% chance.

Does Weathergraph alert me about upcoming rain or snow? #

Yes, the Pro version has alerts for upcoming rain or snow based on the short term nowcast data. on the iPhone and Apple Watch, please ensure you're not in Low Power mode, as the apps are denied background updates in this mode.

Why do I see 'dry' when the humidity is 98%? #

The 'dry' comes from the dew point comfort scale. In the winter, the cold air cannot retain humidity, so even at 98% humidity, there is just a little water in the air, resulting in a dry feeling (and a need to hydrate the skin).

Here is a scale Weathergraph is using, from pleasant at 12 °C to miserable at 25 °C and higher:

If you would like to read more about how this works, Alex has a great article about why the dew point is more respresentative measure, especially for runners.

Common Issues & Troubleshooting

Widgets appear blank, or stopped updating (show outdated data) #

Unfortunately, there appears to be a known iOS and watchOS bug, where the widgets stop updating. The technical reason is that the iOS/watchOS widget system loses track of the file to which it saves the widget data for displaying the widget.

The only fix (but at least reliable one) is to restart the device. Either turn it off and back on, or use the force restart.

I have reported this issue to Apple in iOS 17/watchOS 10, but it seems to be back (but less often) with iOS 18.1/watchOS 11.1, and seems considerably improved with iOS 18.2 and watchOS 11.2.

Widgets aren't updating automatically (and display Update button) #

Please make sure the device is not set to Low Power mode. In the low power mode, background updates are disabled for every third party app, and as a result, Weathegraph cannot update the weather data.

If you don't have Low Power mode on, please try restarting your device.

If the widgets still don't update, please send me the debug logs and we will look into what is happening - thank you!

Weathergraph cannot get the location. #

Please check the location permission for Weathergraph:

iPhone

1. Open Settings on your iPhone, go to Privacy & Security → Location Services → Weathergraph
2. Make sure the permission is set to Always (allows background updates and alerts) or at least While Using the App or Widgets (with this choice, the app can update the forecast only when the system refreshes the widgets)

Watch

1. Open Settings, scroll down and go to Privacy & Security → Location Services → Weathergraph
2. Make sure the permission is set to Always in order for background updates (and alerts) to work. Sometimes, the choices might be disabled - in that case, set the permission on the iPhone instead, as per above.

Weathergraph doesn't update my location unless I open the app. #

Would you please check what location permissions do you have set up for Weathergraph in Settings → Weathergraph → Location?

If there is anything else then Always, could you please pick Always?

Also please make sure the device is not set to Low Power mode. In the low power mode, background updates are disabled for every third party app.

Weathergraph keeps asking for location again and again. #

Please choose Allow while using the app in a permission dialog.
Weathergraph needs to be able to know your location to show actual weather (it doesn't send it to any third party, though — see privacy policy). If you have chosen "Allow once", then the app can only ask for the location once, and next time it will show the permission dialog again.

To change Weathergraph's permission to 'Always allow', please open Settings on your iPhone, scroll down to Weathergraph, tap Location, and pick While Using the App.

Weathergraph's location permission dialog appeared again even though I gave it Allow while using the app access, or I see Weathergraph was denied permission to ask for a location below the forecast. #

It seems that when the application requests the always-on location permission (necessary to allow the app to ask for a location during a complication update in the background), then this permission is reset during WatchOS or iOS update.

I suppose they made it like this to reset permissions once in a while to prevent rogue apps from tracking you forever, but recently, there have been a lot of minor security updates, which triggered the location update screen.

I suggested to Apple (rdar://FB9733269) to only do this with major updates (like 8.0, 8.1 ...), not on every minor security update, but currently, it works like this for the minor updates as well.

I closed the app and it stopped updating in the background #

Are you closing apps on iOS by swiping them away from the task switcher or on mac by quitting the app?

If yes, then the app you close this way is no longer allowed to run or update in the background until you manually open it again.

Please keep the Weathergraph running - it takes care to consume almost no resources.

Subscription Management

I re-installed Weathergraph. How do I restore my subscription? #

On the iPhone:

Please scroll down in the Weathergraph app, tap the Get Pro or Manage purchases button, and on the purchase screen, tap Restore purchases button.

On the watch:

Please scroll down in the Weathergraph app, tap the Get Pro button, and on the purchase screen, tap Restore purchases button.

How can I change my subscription plan, e.g. from Monthly to Yearly? #

Go to Settings - your name - Subscriptions, select Weathergraph and pick a plan you like. Here is Apple's guide.

How can I change from a subscription plan to Forever? #

1. Cancel the existing subscription first:
   Go to Settings - your name - Subscriptions, select Weathergraph and cancel the subscription (see Apple's guide).
2. From the Manage my subscription screen in Weathergraph:
   Select the Forever option, and confirm.

I am not sure if the purchase succeeded — how can I check my active subscriptions (or cancel them)? #

Here is Apple's guide: Manage App Store purchases, subscriptions, settings, and restrictions on iPhone

In short:

1. Open the App Store app on your iPhone.
2. Tap the blue profile icon in the top right corner, then tap Subscriptions.
3. All active and lapsed subscriptions will show up, and you can change or cancel them here.

If the subscription appears here, but you still don't have Pro features in the Weathergraph app:

Please open the Weathergraph app. Scroll down and tap the Check Pro button. Then scroll down on a subscription screen, and tap the Restore Purchases button.

I would like to cancel my purchase or get a refund. #

No problem! Here's how to request refunds for App Store apps.

App Store developers cannot issue refunds themselves, but the link above is quick and easy and almost always quickly approved.

If you have a bit of time, could you please drop me a short email at support@tomaskafka.com and tell me what you didn't like? I'd love to make Weathergraph better. Thank you!

Can I share the subscription with the whole family? #

I have decided to not enable the family sharing, as the subscription needs to pay for weather data.

While it would probably be okay for two people, Apple's family may have up to six people and all of their devices (watches, phones, tablets, macs). With a family like that, and regular background updates for widgets and watch complications, the cost of data could easily exceed the proceeds from subscription.

I got a Pro code, how to redeem it? #

Moodistory has a great simple guide.

Please follow it, then open Weathergraph on your phone (or mac or iPad), open the payment screen, scroll down, and tap the Restore Purchases button.

If you have an Apple Watch, the purchases will sync to them automatically when they get near the phone (no need to run restore on the watch, as it seems to be broken there).

If the restore fails on Mac, please try deleting Weathergraph and installing it again. Thanks!

Technical Issues

Widgets don't appear in the widget picker #

This is a known rare issue in iOS 17 and watchOS 10, so far it seems fixed in iOS 18 and watchOS 11. If you are using the older OS versions, please update your device.

Restarting the device seems to fix the issue.

My watchOS 10 complications are broken, I only see dashes (--) instead of the content #

This seems to be an problem of Apple's migration to a newer watch app format, that developers can do very little about. You can read about the cause in Apple developer forum thread but the tldr is that the migration randomly breakes the complications, as it caches the wrong identifier of the app extension that the complications belong to.

Solution: Please remove all Weathergraph's complications from all the watchfaces at once (this seems to force the watchOS to clear up its old complication data for Weathergraph), and then set up the complications again.

I'd love to know if anyone finds a better way of doing this.

We're solving a technical problem together, how can I send debug logs? #

On the iPhone and Mac:

1. Go to Preferences, scroll down, and tap Debug
2. Tap the Upload logs button
3. Send me the 5-digit number, that appears after the upload, to support@tomaskafka.com

On the watch:

1. Inside the app, scroll down to the bottom and tap the gray version text
2. On the debug screen that opens, tap the Upload logs button
3. Send me the 5-digit number, that appears after the upload, to support@tomaskafka.com

Thank you!

Requested Features

Does Weathergraph support multiple locations? #

Currently, Weathergraph only shows weather for your actual location, but I am working on supporting multiple locations (with favorites for quick access).

Does Weathergraph show governmental weather alerts? #

Not yet, but government alerts are on the roadmap.

How about support for iOS Live Activities? #

It's complicated.

I like the Live activities, but so far they can only be started by some action inside the already opened app. For example, the Uber app can start the live activity when you summon the car, but the app running in the background cannot.

Therefore, the nice use case, where Weathergraph would automatically start a live activity with a precipitation warning when the rain is on the way, cannot happen with the current rules.

It could be hacked around with a notification, that would tell you to open the app, and then the app would set up the live activity to follow the rain progress, but this seems too tedious, so I have stayed out of this for now.

If Apple allows apps to start the live activities from the background, then I'll be happy to revisit this - and until then, I'll keep working on the features I wanted to have yesterday.

Does Weathergraph show air quality? #

AQI is on the roadmap. I already have data sources for air quality, and plan to add them.

Will Weathergraph be available in my non-English language? #

I would love to! However, the engine that creates all the forecast texts is now custom fitted for English grammar. I plan to make this more generic to support more languages, but that will need some time.

Will there be a radar? #

Thank you for the question! Sadly, not anytime soon, as there are a lot of other features in the pipeline, and the radar data are considerably pricier than the forecast data. I'd eventually like to get there, but it won't be quick.

Press kit and chatter

I would like to write about Weathergraph, is there a press kit? #

Of course! Here you go:

• Weathergraph press kit
• Press media and screenshots

What is the story with a similarly named app in the App Store? #

I think we arrived at that name independently, but I am very sure I was first by a couple of years. I have released Weathergraph under that name on Pebble in 2016 and on Garmin in 2017.

I have a different suggestion, idea, or problem to solve #

Just let me know at support@tomaskafka.com — thanks!
