Snapchat update offers in-app purchases (and terrifying new 'lenses')

The ephemeral messaging app has got a little less ephemeral and a whole lot more disturbing

Snapchat has launched its first in-app purchases, offering users the chance to buy the ability to replay already-seen pictures and videos.

The new feature, which is only available in the US for the time being, offers "replays" in packs of three for $0.99. Without them, users can only view any given picture or video once, and get one additional replay for free each day.
