Blue visualizes your 2-day weather forecast in a fast and colorful interface. Swipe up to see hourly weather represented by color in a unique visual gradient, helping you quickly recognize weather patterns and plan your day accordingly.

Hourly colors are calculated based several metrics including the temperature, humidity, and sunrise/sunset times for your current location. Seeing blue? You'll want to grab a warm coat. Seeing purple? Stay inside with a cup of hot cocoa!

Purple - extremely cold.
Blue - cold winter day.
Green - feeling cool.
Yellow - room temperature.
Orange - feeling warm.
Red - hot summer day.
Pink - extremely hot.

Temperatures are shown in either Fahrenheit or Celsius (controlled by your iOS region settings).


Q: How do I change my location?
A: Use your feet. Blue is a minimal app designed to show weather for your current physical location.

Q: How do I change to Fahrenheit or Celsius?
A: Blue automatically shows the appropriate unit for your selected country/region. To change your region go to iOS Settings > General > Language & Region > Region. All regions use Celsius except United States, Bahamas, Belize, Cayman Islands, and Palau which use Fahrenheit.

Q: How do I change my language preference?
A: Blue will automatically use your preferred language where possible. To change your language, go to iOS Settings > General > Language & Region > iPhone Language.

Good concept, but…

Blue is a wonderful weather app, but if it really wants to make use of this "scroll for a forecast" thing, it should at least allow easy scrolling all the way to the final forecast hour. Other than that, five stars.

No updates ..inaccurate weather...dead app?

I have been a strong proponent of this app for several years now and have found it to be one of the most simplistic yet accurate and useful tools of all my apps.
You wanna know the temp right now you got it, you wanna know in 3 hours what to expect you got that too, you want to track the start and stop times of some oncoming weather thing and this app was spot on accurate down to within about 10 minutes no joke!
I loved it but the last two weather events about to roll in my area, and I pull out my most trusted weather app to find out then”real” story, it tells me no bad weather just a couple hours of light flurries, so the weatherman and everyone are wrong again...within minutes it started to dump snow and the app had it clear or light flurries. I ignored it as a glitch but today similar thing, schools are closing as a proactive measure and when looking at the app, for a few hours they show a light chance of light flurries then clear!
Inaccurate weather reports are about as good as a sandbox in the desert!

Seems there is no support or updates so to me it’s a delete, with a warning to others, I wouldn’t trust this application if I were you!

Am deleting now!
