What you need to know about Frontier mobile apps
There is an iOS app from Frontier which will work on your iPhone, iPod, or iPad.
For Frontier EarlyReturns 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 Frontier 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 Frontier.
Also take a look at Frontier's website by clicking here — you should be able to do what you need there.
