There are two apps becuase not all e-tron come with the Tech package which comes with MMI Connect. I spec'ed my premium plus e-tron without one. But all US bound A3 e-tron can use the e-tron Connect app. The must have for me was the color combo (scuba blue and gray interior - which makes a lot of difference, since it makes the interior feel airy and bright and not so depressingly dark). So far I have over 9,700 miles on it and averaging about 5.5 mi/kWh.
