If This, Then That

IF THIS THEN THAT is a free online service that allows you to connect many different online services together. The idea is simple, if a certain thing happens on one web application, then do something on another. For example, if someone tags me in a photo on Facebook, then save a copy of that picture to my Google Drive account.

IFTTT also works with devices like the Belkin Wemo, UP wristband by Jawbone, Withings, and the Philips Hue bulb.
