Yes, we recently released the first version of the Upgrade mobile app which allows customers to manage their Upgrade account on the go. We're already working on more features that we'll add in the next release, so stay tuned! If you have questions or feedback on the app, we'd love to hear from you at email@example.com.
The Upgrade mobile app supports Apple users with an iPhone 7 or newer running iOS 9 or later as well as Google users running Android 6 (Marshmallow) or later. You can download the Android app here, and the iOS app here.
