Swackett® for macOS, version 5.2

Swackett has been "a whole new way to look at weather" since 2010. We convert complex weather data into easily-understood visual weather reports — designed for people of every age.

Our unique approach is to combine raw weather data (current conditions, radar, satellite imagery and detailed forecasts from multiple data services) with thoughtfully crafted people symbols (affectionately called "Peeps") who always appear appropriately dressed for the weather.

If Swackett Peeps appear sporting sunglasses, wearing a jacket, or carrying an umbrella — you probably should be too.

in 2018 each Swackett app has been been carefully re-built using state-of-the-art technology — technology built with a user’s privacy as a chief concern — resulting in new Swackett tech affectionately referred to as the IQ Weather Engine.
