What exactly is Whocalld? From the article I assumed it was a way to find out what that unidentified number in your call history was without having to pay for it like all those sketchy services, which is awesome. But the actual site says literally nothing, not one word, about what it is. There's the name; a phone number entry field; a random, enthusastic, uninformative user endorsement; and then...um...a bunch of recordings of one side of a random phone conversation. The recordings are completely unlabeled but do helpfully display foggy widescreen audio wave forms. They have play buttons but no stop buttons.
So...that's really creepy. What is this thing?
