Dark Sky is the most accurate source of hyperlocal weather information. With down-to-the-minute forecasts, you’ll know exactly when the rain will start or stop, right where you’re standing. (It’s like magic.)

Featured in: New York Times, Wall Street Journal, Fast Company, Wired, and more.

Dark Sky is able to create forecasts for your precise location, giving you minute-by-minute predictions for the next hour and hour-by-hour forecasts for the next day and week.

The same technology that powers Dark Sky’s predictions also allows us to make the world’s first perfectly smooth radar animation. Other apps show you a chunky slideshow that makes it nearly impossible to tell how storms are moving. But Dark Sky’s radar animation lets you see the actual path of the storm: how it moved in the past, and where it’s going in the future.

Dark Sky comes with advanced notification options: Receive down-to-the-minute alerts before it starts raining at your exact location, get notified of government severe weather alerts (for such things as thunderstorms, flooding, hurricanes, etc.), or even create your own custom notifications covering the next 24 hours for things like temperature, wind, precipitation and more. Even if you haven’t opened the app in days, Dark Sky will tell you what you need to know, when you need to know it.

The Dark Sky Notification Center Widget tells you at a glance what’s going to happen in the next hour and the next week, so you don’t even have to unlock your phone to quickly check the weather before heading out.

Explore weather in the past or future. Choose a date and see historical weather data or future predictions based off of seasonal averages.

Dark Sky looks great on your wrist. Get notifications and check out the weather for the next week with the Dark Sky app built from scratch for Apple Watch.

Editors’ Choice

Being able to track atmospheric pressure to the nearest millibar sounds impressive and all, but sometimes you just want to know if it’s going to rain. Dark Sky tells you exactly how much precipitation to expect and when to expect it, as well as offering cool customizable weather alerts and a mesmerizing time-lapse view of local cloud movements that’s almost as much fun as splashing in puddles.

Can’t take all this CHANGE!

For years Dark Sky has been unique in providing information about incoming rain and precipitation with uncanny precision and an amazingly driven by a simple yet timeless animated graphical interface. Now it’s been “rewritten” to look like a “regular” weather app with dare I say dull, uninspiring interface. That said there is new and welcomed functionality in this version that improves the forecast and most notably adds a really cool “TIME MACHINE” function allowing users to view past and future weather forecasts by date on demand. All that said, being that this new graphic interface is somewhat uninspiring the question arises as to why the new features weren’t simply added to the winning look of the original app? Surely there are reasons that end users will never know, but perhaps the developers, Jack Adam can take pity on those of us who have a difficult time with change and consider offering us a choice to display a “classic” mode that will bring back the original look? If that’s just a pipe dream, how about integrating a bit more of the classic blue color into the current scheme to spice up the mostly monochrome grays as a nod to the Dark Sky many of us longtime users can appreciate in the name of nostalgia? 4 stars for now since this app still rocks in functionality, but the fifth star will be reserved for a future update or until this user can embrace the change.

Finally, I have downloaded over 30 weather apps

I live in SW Florida and aside from hurricane season, we can have quickly changing weather and circumstances. Lately, it's been wildfires and lack of rain with crazy winds makes for a dangerous situation. One which you need to trust the weather data your receiving minute to minute. Dark Sky is that App for my family. I have easily downloaded & tried over thirty weather apps and have found Dark Sky to be the most accurate and easy to use GUI available. Where I live buts right up to the Everglades, in fact we are part of the Everglades, so I was initially concerned with coverage and the use of other user input with the weather their experiencing near them. I have found the coverage is unbeatable and the data from other users is brilliant and comes together to make the most accurate & current weather information available. I work in emergency services and I use Dark Sky to compare against info I get from national services & the local EOC information and to my surprise, the user data makes the difference to understand what's happening not only in my area but others I look after. Few Apps have I ever rated 5 stars. I also would like to thank the app developers for consistently updating & working through bugs quickly.
