The latest info on Qatar Airways mobile apps
Qatar Airways provides an iOS app that is compatible with iPhone, iPod, and iPad.
For Qatar Airways Privilege Club members, you'll be able to manage your account from the app, though using their website will no doubt provide more functionality
The Android apps from Qatar Airways work with all Android phones and tablets from various manufacturers (Samsung, LG, Google, etc.), and Android Wear watches might also be compatible. As is often the case, the Android app offers the same functionality as the iOS app.
