Seasonality Core is a Mac utility designed to give you access to accurate weather information. The application features a straightforward interface, brings you a comprehensive help manual, and allows you to monitor weather forecasts for multiple locations.
If you want to use the program to monitor weather info in your area make sure you grant it permission to identify your current location. Afterwards, the app will display various weather details, such as temperature, wind speed, humidity level, etc.
Furthermore, you can use the built-in search tool to look for other locations from around the world. The app will monitor the weather info for all of the areas located on the left side of the interface.
The only thing I'd change would be to add a small menu, preferably placed on Mac's Menu Bar, to immediately give you access to the weather information you need. Other than that, nothing bad can be said about this application. It works 100%, provides you with accurate weather details, and comes with a reasonable price.
You can find cheaper solutions, like using your default web browser to go to weather-related websites or other desktop weather apps. But I still think it's worth buying this program, especially if you're the type of Mac user who wants to constantly keep track of weather info.
