Apple killed Dark Sky. Now its creators are trying again with a new weather app

Dark Sky was a rarity in the app world. Universally beloved, the weather app had an uncanny ability to tell you when to expect rain, down to the minute. So when Apple announced plans to buy it six years ago, there was a collective sigh of frustration.

The Android version, of course, disappeared almost immediately, while the iOS version was folded into Apple’s native Weather app. (The standalone iPhone app was discontinued.) The integration was never quite the same, though, and it seemed as if the magic of Dark Sky was lost. Now, however, the team behind the app is hoping lightning strikes twice.

The developers of Dark Sky have announced a new iPhone app called Acme Weather, a tool meant to address the uncertainty inherent in meteorological forecasts. (An Android version is forthcoming.)

“It is a simple fact that no weather forecast will ever be 100% reliable: the weather is moody, fickle, and chaotic. Forecasts are often wrong,” the team writes in its announcement blog post. “Rather than pretending we will always be right, Acme Weather embraces the idea that our forecast will sometimes be wrong.”

In practical terms, that means Acme Weather, which comes with a two-week free trial and then costs $25 per year, offers its best estimate for a range of weather data points, including temperature throughout the day (as well as the feels-like temperature), dew point, humidity, and more. Those predictions appear as a dark line. Alternate possibilities appear as lighter shaded lines layered on top.

The closer those lines are to each other, the more confident the forecast. A wider gap signals more uncertainty, suggesting you may want to monitor conditions more closely and check the app more frequently to see how things are trending.

The homegrown forecasts, the team says, will be even more accurate than those in Dark Sky, thanks to a wide range of data sources, including numerical weather prediction models, satellite data, ground station observations, and radar.

The app will also incorporate community reports, letting people share conditions in their area. That could be especially helpful during severe weather, as radar is not 100% reliable. It has trouble, for instance, recognizing the difference between freezing rain and snow sometimes.

Reporting the weather is simple: Choose the icon that reflects current conditions. And, if you’d like, you can add commentary by selecting an emoji to reflect how the weather feels. (Yes, the poop emoji is an option for particularly rough days.)

Just note that by using the community reporting feature, you will disclose your location to other users. While the app doesn’t reveal an exact address or identifying information, it does display your location on the map at the time of reporting with a fairly high degree of accuracy. (Community reporting is completely optional, but cannot be withdrawn once submitted.) The company, in its announcement, pledged not to collect unnecessary data, use third-party trackers, or sell user information to advertisers.

The app also features the maps you would expect, including radar and lightning. It will offer rain and snow totals, hurricane tracks, and cloud cover. And, like Dark Sky, it will alert you when weather is approaching. This time, though, you can customize alerts based on what you care about, from rain to nearby lightning to the possibility of a rainbow or especially striking sunset.

“We’ve been making weather apps for 15 years, from Dark Sky to Apple, and this is the culmination (the acme?) of everything we’ve learned along the way,” the blog post reads. “It’s the weather app we’ve always wanted, and always wanted to build.”
