What happened to the Boo app?

I'm curious to know, what exactly transpired with the Boo app? It seemed to have gained quite a bit of traction and popularity in its heyday, but now it seems to have vanished into thin air. Did it suffer from a lack of funding? Was there a security breach that led to its downfall? Or did it simply fail to keep up with the ever-evolving demands of the market? I'm eager to hear your thoughts on what might have caused the Boo app's demise.
