With minimal effort, we can recall what yesterday’s weather felt like to us. We can quickly tell if we are cold, hot, or humid without the need for quantitative details. Most weather apps give information about the present day and future forecast. Instead, inspired by stock market apps, Retro Weather displays the trend compared to yesterday’s weather, offering users information whether temperature, wind, pressure, and humidity will increase, decrease or stay the same. In addition, the app mimics the current sky color in the background and overlays subtle animations that relate to how the weather phenomena would interact with your phone’s glass screen.
