The recipe-based automation software IFTTT delivered its one-button control app to phones back in February, and now it's putting it on your wrist. Android Wear gadgets can now employ the DO Button to complete any number of tasks that you assign to it. Rather than waiting for certain criteria to be met in order to trigger an action or swiping over to the requisite app, a single button push handles the chore. We're talking about things like setting your Nest thermostat to 68 degrees or turning off those Phillips Hue lights. Looking to take the DO Button for a spin? Grab the app from Google Pay and you'll be able to do just that.
