Forecast is updated every hour, and cached offline — the chart always shows current temperature according to last obtained forecast, even when you go for a long run without your phone.

You can unlock professional Dark Sky forecast and all themes with a reasonably priced subscription, which covers a cost of data and allows me to further improve Weathergraph.

Thank you!

Frequently asked questions #

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 in order 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.
I cannot reinstall Weathergraph, I only see a Purchase button on my iPhone and it is disabled #
Please just open App Store on your watch, search for "weathergraph', and there you will be able to install the app.
This is an oversight not yet fixed by Apple - for some reason, independent (= watch only) apps can only be reinstalled from the watch.
I installed Weathergraph and I would like to restore my subscription #
Please tap the Get Pro button, and in a purchase screen, tap Restore purchases button.
