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 via reasonably priced subscription, which covers a cost of data and allows me to further improve Weathergraph.

Thank you!
