What you need to know about Singapore Airlines mobile apps
There is an iOS app from Singapore Airlines which will work on your iPhone, iPod, or iPad.
KrisFlyer members will also be able to use the app to manage their profile, view account activity, and more right from the app.
The Android apps from Singapore Airlines 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.
