"If This Then That" is a way to easily automate tasks in your life.
If This Then That (also know as IFTTT) is a way to easily automate tasks in your life. It can be automatically saving photos that you're tagged in on Facebook to Dropbox, a security alert if your family members calls for emergency services, or even if you want your coffee pot to automatically turn on when you wake up in the morning. IFTT's customizations are practically endless.
To create an automation you use a recipe; for example you may want your phone to send you a reminder to take an umbrella if it's going to rain. So you can tell IFTTT to set up a recipe as follows: "IF" forecast for today is rain, "THEN" send reminder to take umbrella.
