How mobile-friendly is KLM?

There is an iOS app from KLM which will work on your iPhone, iPod, or iPad.

For KLM Flying Blue 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 KLM 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 KLM.
