That phrase is pretty bad.

Cross platform? Does this mean it runs on Linux and Macos? POSIX? Does it run on Windows? VMS? AIX? Apple Watch?

Simplified from what?

Monitoring what? Babies? Computers? Nuclear proliferation?

That phrase is not bad. But even this project can be better described via a table that compares it with alternatives.

Good idea, I will think how to improve both, the landing page and the GitHub's readme file.
