Dark Sky can tell you at a glance exactly when it will rain (or snow) up to an hour in advance, so you’re free to walk the dog or run out to lunch and know you’ll stay dry. You can also explore the most beautiful weather animation you’ve ever seen, both forward in time or back.

(Dark Sky is available in the US, UK and Ireland.)

Using GPS, Dark Sky is able to create forecasts for your precise location, giving you minute-by-minute predictions for the next hour and hour-by-hour forecasts for the next day and week.

The same technology that powers Dark Sky’s predictions also allows us to make the world’s first perfectly smooth radar animation. Other apps show you a chunky slideshow that makes it nearly impossible to tell how storms are moving. But Dark Sky’s radar animation lets you see the actual path of the storm: how it moved in the past, and where it’s going in the future.

Dark Sky comes with advanced notification options: Receive down-to-the-minute alerts before it starts raining at your exact location, get notified of government severe weather alerts (for such things as thunderstorms, flooding, hurricanes, etc), or even create your own custom notifications covering the next 24 hours for things like temperature, wind, precipitation and more. Even if you haven't opened the app in days, Dark Sky will tell you what you need to know, when you need to know it.

The Dark Sky Notification Center Widget tells you at a glance what's going to happen in the next hour and the next week, so you don't even have to unlock your phone to quickly check the weather before heading out.

Dark Sky looks great on your wrist. Get notifications and check out the weather for the next week with the Dark Sky app built from scratch for Apple Watch.

Being able to track atmospheric pressure to the nearest millibar sounds impressive and all, but sometimes you just want to know if it’s going to rain. Dark Sky tells you exactly how much precipitation to expect and when to expect it, as well as offering cool customizable weather alerts and a mesmerizing time-lapse view of local cloud movements that’s almost as much fun as splashing in puddles.

Really useful App


Only had this app for a week, but it's already proved invaluable. When deciding when to have a BBQ, it predicted rain on the Sunday, which happened, and warm and sunny on the Monday, which also was correct. Our decision, in advance, to have our BBQ on the Monday rather than the Sunday, was therefore perfect. So far the warnings of rain or even drizzle have been spot on. I have had a couple of Met Office weather apps for years, but this is by far the best I have seen so far. Time will tell whether such accuracy will continue over a full year, but so far, so good.

Well, I’ve now used this app for the best part of a year and it has not disappointed at all. Really useful prediction tool, and I can definitely recommend it.

A little embarrassing at times


A little embarrassing at times when trying to convince friends and family that this app is reliable... I am mostly referring to the use on my Apple Watch 3.

I’m going to stick with this a little longer to give it more of a chance, however when using the Apple Watch the screen can stay static (if use on watch face / home screen) and stay on ‘rain starting soon’, it can do this with being clear but then it rains....

The watch part of this app needs sharpening up, I did try to email the developer before Christmas but I haven’t heard back (5th January 2018 today’s date).

Otherwise the app on my iPhone works well, but still not spot on, as for instance it said ‘possible rain for 1pm, but 76% chance of rain for 3pm’, there was no rain until late evening around 10pm. But hey ho, sometimes the weather reporter gets this wrong.

So all in all, it’s been good with the iPhone but sluggish with the Apple Watch, I will give it a bit of a chance as the Apple Watch 3 is still fairly new and it may be down to software adjustments... (probably).

But still would like to hear back from Dark Sky via email.
