The latest info on Ryanair mobile apps
Ryanair provides an iOS app that is compatible with iPhone, iPod, and iPad.
For Ryanair Ryanair Airlines Frequent Flyer Program 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 Ryanair work with all Android phones and tablets from various manufacturers (Samsung, LG, Google, etc.), and Android Wear watches might also be compatible. You can get the same stuff done on the Android app as you can on the iOS app for Ryanair.
If you're just looking for their mobile site, you can head on over to http://www.ryanair.com on your mobile device.
