How mobile-friendly is Austrian Airlines?

The iOS apps from Austrian Airlines will work with all of your Apple devices, from iPad to iPhone

Also, if you're a member of Austrian Airlines Miles & More, you can manage your profile, view your points balance, and more.

The Android apps from Austrian Airlines work with all Android phones and tablets from various manufacturers (Samsung, LG, Google, etc.), and Android Wear watches might also be compatible. Perhaps standard practice these days, the Android app offers the same functionality as the iOS app from Austrian Airlines.
