>> well, it's a game that we're never going to really solve -- >> you sound like a meteorologist now. >> i think we're getting closer. but basically what we do is take a bunch of people's contributions, decide if they corroborate. if they all match up in a certain small area, we update the forecast and we'll send you a notification to say, all our things are pointing to the fact that it's going to rain on you in the next five minutes. >> what are you finding in terms of how your app matches traditional weather forecasting apps? are they pretty much in line -- >> we're getting much better accuracy. there's a reason why we're focusing on the east coast because most of the weather comes off the land across from the west coast. this kind of app -- and predicting weather across the west coast is much tougher because it comes over the water. so we are in a much better position here because we have people all along and the weather travels from west to east. >> justin re, it's called the minutely app.
