>Plus a very expensive (relatively) subscription. I loved Dark Sky because I bought it and then I had it.
Ongoing customer value (hyper-local precipitation forecasts) that has ongoing costs for the developer (weather data) is unsustainable without ongoing revenue (subscriptions). This may have had a thing or two to do with Dark Sky ending in an acquihire.
There’s RainAlarm which achieves a similar feature by downloading (freely available) radar imagery and notifying you when the rain echoes are nearby. Worked pretty well when I used this a few years ago. (I’ve now moved to a country where Apple’s rain warnings are pretty accurate.)
The 'ring' data view at the top (and bottom of the second image) is a nice way to represent the data in a limited amount of space (phone / watch widgets).
