Dark Sky - Weather Radar, Hyperlocal Forecasts, and Storm Alerts


Dark Sky can tell you at a glance exactly when it will rain (or snow) up to an hour in advance, so you’re free to walk the dog or run out to lunch and know you’ll stay dry. You can also explore the most beautiful weather animation you’ve ever seen, both forward in time or back.

(Dark Sky is available in the US, UK and Ireland.)

Using GPS, 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, so you don't even have to unlock your phone to quickly check the weather before heading out.

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.

Super accurate way to predict rain. Formats nicely to the 4" screen except when in a phone call.

weather done differently... nice twist on the usual. Wonder if it's going to rain? This thing is a bit uncanny, but darned handy.

One of my favorite weather apps. Unfortunately I believe it is U.S. only at the moment. That said, for us Colonials, its accuracy is downright amazing. You can turn on notifications on when it will start to rain/snow. I've found the timing to be within the minute and it's very handy for determining weather-gear for the next 24 hours.

Hard to recommend for the price, but cool and useful weather app for sure. Gets right to the heart of what a weather app should answer: "What's it like out for the next hour or so?"

Was working in The West Indies on a Tennis Channel shoot, on the Island of Nevis. This App provided very accurate radar and a well designed interface. I recommend it for checking if rain or bad weather is headed your way. U can set an alert to be notified for Rain OR Snow. I live in Los Angeles saw I'm looking forward to getting a Notification for the Rain setting. I rarely pay this much for an app, but this one is worth if u like to check the weather.Dark Sky - Weather...

Finally a super accurate app for precipitation predictions for exactly where you are located at the time. Perfect for deciding whether to venture out for a bike ride or a run. It's been spot on for me, even in unpredictable Florida.
