IFTTT is a web service that allows you to create custom recipes to make online actions automatic. There are currently 67 services, each having their own actions, available with more being added. Dropbox, Instagram, Facebook, WeMo, Phillips Hue, and Gmail just to name a few.
The concept is simple; If ABC, then XYZ. One recipe I have enabled is if my Facebook profile image is changed, then my Twitter profile is changed. This is very handy as it saves me time from having to go back and change it. The team over at twit.tv did a nice show on how to make the most out of IFTTT.
I absolutely love the service and there are thousands of automated actions to chose from. Having the power to do this right from your iPhone is amazing. The service is available for FREE. Get to downloading and share your favorite recipes with us in the comments or on Twitter.
