True, but the app's README does say

Of course, after writing this, Apple released their uuidgen command line tool. While that certainly has its place, UUID Generator provides UUID generation via a GUI, a Service, and in various convenient formats.

Yes, you could use uuidgen. UUID Generator is free, and does a lot more than the system-provided uuidgen.

As stated, UUID Generator was originally created before Apple provided uuidgen. The main reason I revamped it after all these years is because it came to my attention that the OS provided an additional facility for generating UUIDs. The algorithm uuidgen (and CFUUID) use is based upon time and Ethernet MAC address, which has security implications. UUID Generator provides this approach for those that want it, but it now also provides a pure random (/dev/urandom) based UUID generation (through the e2fsprogs library).

Furthermore, UUID Generator outputs the UUID in various formats to various output locations, and UUID generation as a System Service. These conveniences, along with a more secure UUID generation algorithm, are what make UUID Generator useful.

If uuidgen works fine for you, by all means continue to use it.
