I made a weather app design as a design exercise recently. It is heavily inspired by Material Design as that was part of the brief.
Some added features
There’s not much to add really, although I made a lot of considerations about context and how a weather app should be used today. Which brought me to the idea of having a forecast subtitle, which tells you if you need to bring something (an umbrella, a jacket, etc.) or simply summarize the weather until you do need to bring something.
There were indications that I wanted a filter system which would de-clutter the overview. The thought behind that is the ability to “collect” weather cards and still keep a relatively simple Overview screen that doesn’t scroll for forever.
