Video: See How Dark Sky Disrupts The Weather Report With Its Mobile Tech

Jack Turner and Adam Grossman were sick of getting stuck in the rain, so they created an app that predicts rainfall in hour-long intervals.

For the creators of Dark Sky, having a TV meteorologist predict the week’s weather wasn’t good enough. They needed something more personal. They needed something more immediate. So Jack Turner and Adam Grossman created an app that utilized government data to predict rainfall at a user's exact location and at that exact moment.

"Starting this out we had zero experience with weather technology," says Grossman. "We were just sick of getting stuck in the rain, and here’s a government that just gives you radar data for free."

The app got its startup funding in 2011 from Kickstarter, where it raised nearly $39,400 in a month. Today, the pocket-sized weather service sells for $3.99 on iTunes. Dark Sky predicts rainfall at the location of the user for a period of one hour. The perfect amount of time, according to its creators.

"The next hour is when you have to walk the dog, it’s when you have to run to the corner store," Turner says. It's also the difference between holding your wedding ceremony inside or out by the lake, which was part of the app's genesis.

Fast Company met up with Grossman and Turner in New York’s Central Park for a test drive of their creation.

    This app is awesome! It actually makes you feel in control of how you deal with weather. For example, I could check the weather all day at my desk to know when the best time to leave might be. Or I could have Dark Sky send me a push notification Hollywood style! Their people 'call' my phone. I can't tell you the number of times I've gotten a push notification and _exactly_ 15 minutes later... it rains. This is the only weather app I need. It is the only app that helps me decide, 'Do I leave now?' and 'Do I need an umbrella?'. I don't need to know what will happen three days from now because it will probably be wrong (excluding rare major weather events).

    Usually I like to give some contrast for reviews... lets see... the app is polished, the radars are an order of magnitude better/smoother than anything else out there... ah maybe the colors are not my style.

    In the end I would pay at least 2x what they originally charged ($20).

    Did the writer of this use the app? The writer would have quickly found out that the marketing far out weighs the accuracy. Non-meteorologists would think it was so easy to accurately do this, but even their app shows it does not. Don't expect it to snow/rain/sleet in xx minutes as the app will tell you. The developers should have stuck to threats (probabilities) as opposed to definitives - far more useful for planning than waiting for an app to tell you it will, or won't rain in 10 minutes. Be skeptical of this app.
