One of my favorite apps, Dark Sky, got a major facelift today with the release of 6.0. If you haven't heard of it before, Dark Sky is the most magical weather app out there.
It tells you when and how much it's going to precipitate (rain, snow, golf ball-sized hail, etc.) up to minutes before you're caught outside unprepared. I was skeptical at first, but it's saved me many times.
The app isn't free though. It costs $3.99. That might seem like a lot, but it will pay for itself the first time it alerts you of incoming rain. Also, it's hyperlocal weather forecasts make you feel like you have superpowers.
If you're on iOS, you can check it out on the App Store here.
