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 #

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