Seasonality Go: Customizable Advanced Weather Display and Wind Simulation


Seasonality Go turns your iPhone or iPad into a complete weather center. Gathering data from sources all over the world, Seasonality Go is the last weather app you’ll ever need.

For the iPad, Seasonality Go provides several built-in screen layouts, and also allows you to create your very own screens with exactly the weather data you want to see.

On the iPhone, Seasonality Go presents all the same data in a clean view of the past, present, and future weather.

The interface in both versions of Seasonality Go have been optimized to dedicate as much of the screen as possible to showing weather data. No extra cruft and never any ads. Some key features of Seasonality Go include:

• Search over 65,000 pre-defined locations in more than 200 countries, or use your device’s built-in GPS to get precise local weather data anywhere in the world.
• Current weather conditions and astronomical data like sunrise/sunset times and moon phase.
• A 7 day forecast in a day/night view or a 3 hourly view.
• Graphs for 10 weather variables including temperature, wind speed, precipitation, cloud cover and more…
• Animated map with radar imagery in the US, Canada, and Australia; and infrared satellite imagery worldwide.
• A surface analysis map layer showing fronts and high/low pressure centers over North America.
• A worldwide wind simulator called Particle Mode.
