POME
A folded card, written on an iPhone Duo and passed in Messages.
POME, by Petrichor Studio, turns an iPhone Duo into a folded card: the outer display is the cover, the inner display is the inside, and folding the phone folds the card. Write on it, then pass it in Messages. Nothing of a pome is ever on this site: a pome goes from one phone to the other and nowhere else.
If a POME bubble brought you here, the pome is in the link itself and never reached this site. Open the bubble in Messages on an iPhone with POME.
