It says they took some inspiration from the DIY pwnagotchi [https://pwnagotchi.ai/]

I have most of the parts to do the individual tasks this thing is supposed to do. What I don't have is the time or desire to whip it all up into a functional tool including a display, buttons, etc. It doesn't do anything that you can't do right now with parts available from SparkFun/Ada Fruit/etc. It's the form factor and interface that makes it desirable.

In fact the form factor is too sexy for its own good in that it made it so desirable it has slowed down development as they had to go backwards in development to include several kitchen sink features that should have been left behind. But hey I'll take an extra kitchen sink when it comes.
