How mobile-friendly is EVA Air?

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

As a member of EVA Air Infinity MileageLands Program (and we always recommend joining loyalty programs, you can use the app to manage your account, view upcoming reservations, and more.

EVA Air has an Android app that works with most Android tablets, phones, and some Android Wear devices. Perhaps standard practice these days, the Android app offers the same functionality as the iOS app from EVA Air.
