Useless
32.6 MB of useless info, no gate info, no push notifications, nothing you would expect from an airport app. Mind that this is a very busy airport during summer a hub as the Greeks like to often mention. The only thing which is worst than the app is the webpage. To get flight info you need to click at least 5 times, register with your email, approve the registration to receive flight info like you are signing a contract to buy a flat. Once done guess what is missing, the gate info again :) Both webpage and the app must be an outcome of A/B or usability testing. NOT!
