The latest info on China Airlines mobile apps

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

For China Airlines Dynasty Flyer 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 China 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 China Airlines.
