I find the app really good. In fact I find it easier to book via app rather than on the website. You can also book a flight with your frequent flyer points which I find very convenient. The app also features a newsstand where you can download your favourite papers 24h before the flight. If you are a Eurobonus member you can also view your account activity in a clear and concise manner. Last but not least I find the Nordic touch in the design (wooden background) quite pleasant.
