What happened to the egg app?

I've been wondering, what exactly happened to the Egg app? I remember using it regularly for its unique features and convenience, but lately, it seems to have disappeared from the app stores. Is it still in operation, or has it been discontinued? If it's still around, why can't I find it anymore? And if it's not, what led to its downfall? I'm really curious to know the story behind this once popular app.
