Not a plug, I’m not involved with it in any way, but I love the iPhone app, Dark Sky. It zeroes in on your location (more accurate on wi-fi, but still close on 3G/4G), and it tells you just the weather for the next hour. Sounds not-useful, but if you want to know if you need an umbrella to run to the coffee shop and back, or if you should leave the bar now or have one more drink, this app will tell you, “it’s going to start raining in 7 minutes”. And while it can never be 100% accurate, it’s something I rely on a lot. I just used it to get down to 9th Street Espresso and back before the downpour. And since the clouds, oddly, moved in from the east and not from the west, I could easily have looked outside and thought it was clearing up, not getting ready to rain. It’s not a free app, but I’ve never once regretted buying it. Developers need to eat, too, and thank god the app has no ads.
