Fred Nerby is designer from Australia who has an impressive expertise to make design concepts for huge brands, such as Facebook, Nike and Twitter.
Coolcal is a simple and easy-to-use weather calendar application that will make your day better. That's the description from one of the guys behind it and they have a different approach on how to present the calendar information. It's a simpler an minimal attempt to change how we use calendars. I have to say, from the mocks they share on Behance it looks gorgeous, I can say much about the UI/UX before using it but from what I see it makes me want to definitely give it a try.
The folks from Netguru are the ones responsible for the application and they are being so kind to share a bit more about the design and development process on their website. They also have some freebies like the weather icon set. For more information check out their Behance profile.
