We recommend checking the downloaded files with any free antivirus. The actual developer of this free Mac application is Snapwise Inc. The program lies within Internet & Network Tools, more precisely RSS Tools.
From the developer:
Ground News is a platform that makes it easy to compare news sources, read between the lines of media bias, and break free from algorithms. If you are like the many people who feel overwhelmed and under-informed as they piece together patchwork information from social media and conflicting news sources, Ground News will empower you with an array of visualization and comparison tools that makes it simple to analyze, understand, and draw your own conclusions about a developing news story.
You may want to check out more software for Mac, such as AmphetaDesk, rhetoris or iht reader, which might be similar to groundnews.
