Weather forecast app, with uncertainty as a core feature

The folks who made Dark Sky, my once go-to weather app that was inevitably acquired by Apple, are back with a new weather app: Acme Weather. Instead of oversimplifying a forecast only to show what is most likely, you also get other possible ways the day can go.
Understanding this uncertainty is crucial for planning your day. Most weather apps will give you their single best guess, leaving you to wonder how sure they actually are, and what else might happen instead. Will it actually start raining at 9am, or might it end up pushed off until noon? Will there be rain or snow? How sure are you? You can’t plan your day if you don’t know how much you can trust the forecast, or know what other possibilities might arise. Rather than pretending we will always be right, Acme Weather embraces the idea that our forecast will sometimes be wrong.
Embracing uncertainty. Just like the Nicolas Cage title character in the movie The Weather Man. It’s not just wind.
They also have fun things in the works like rainbow alerts and beautiful sunsets. I might have to switch.
