I always know when it’s going to rain. It’s not because I’m psychic, but because of Dark Sky, which I can confidently call one of—of not the—best weather apps in the App Store. Originally funded through a Kickstarter campaign, the success of Dark Sky has brought about Forecast.io and a robust weather platform for other great apps.

What does two years of development and going back to the drawing board get you? A complete redesign of Dark Sky for iOS. I’ve been using it for months, and it’s finally available in the App Store as a free update.

Dark Sky, the Instapaper of weather apps, just hit v4.0. It’s still only available in the U.S and the UK, and it still gives you accurate, hyper-local predictions for rain, but just about everything else has changed. For the better, I might add.

Dark Sky, our favorite micro-weather app for iOS, has just gotten a beautiful update to the big three-point-oh. Dark Sky’s just as simple as it ever was, but gives you a little more information about weather farther than an hour away, the ability to submit a personal weather support and meteorological data for our friends over in the U.K. Neat!

Remember the app Dark Sky? If you’re outside the U.S., what you’ll remember is the frustration of not being able to use its amazing real-time rain warnings, which would literally tell you when it would rain on your location in the next hour or so.

Now, the developers of Dark Sky have come out with Forecast, which works anywhere in the world, and will run on Android, iOS, the desktop, anywhere. How? It’s a web app.

If you visited the site yesterday, you’ll already be aware that Cult of Mac’s weekly must-have apps and games roundups are now back. This is where we choose our pick of the best new releases and updates to hit the App Store in the past week.

This week’s feature includes the official Klout app, which has finally made its way to iOS; a great service for storing and syncing your passwords from security specialists Norton; a beautiful weather app, and more.

As an Englishman, I know all about rain. I’m intimate with sleet, drizzle, and driving rain both horizontal and vertical. I know about rain that slowly soaks you even though it seems that none is falling, about freezing rain that stings as hard as hail, about the rain that seems to ignore your umbrella and creep into even the best-sealed seams of your clothes.

Other countries might have spectacular monsoons, or driving rainstorms that flow for days, but for variety and ubiquity of precipitation, it’s hard to beat the British Isles. Which is why I’m sad that Dark Sky — an app that predicts the rain forecast for the next hour only — currently only works in the continental United States.
