It's a breeze to get the outdoor temperature on your phone. But to pull up the climate indoors, you'll need Thermodo. The add-on plugs right into your phone's audio jack, and you can use it to find out the temp wherever you are. It can help you keep any room at the perfect temperature for cutting energy costs, and you can even make sure the fridge and freezer are functioning optimally.
