Is there a good "To Do" app for iPhones that works with Siri?

I am looking for a good "To Do" app for iPhones -- probably not made by Apple -- that works with Siri recording for input and output. I.e., it should respond to, "Siri, add 'drop off cleaning' to my To Do list," as well as reading aloud the list in response to, "Siri, read me my To Do" list. If the app also provided a print possibility, -- i.e. "Siri, print my To Do list" (assuming, of course that I have a printer available and linked to my iPhone) that would be great.

Any recommendations?
