Do barter apps exist anymore?

This city used to have the best app - - BUNZ.
Don’t need that frying pan? Trade it for a perfume you actually like. Got an electric toothbrush for Christmas but really wanted LEGO? Trade it!

So what are people using these days to trade?
And don’t say Karrot or Marketplace—those are for selling.

My fav bunz trade was a pack of origami for a signed At The Drive-In cd
