The SubAssistant app is free mobile application for smartphones and tablets that provides an easy-to-use interface for your SubAssistant account and allows you to receive push notifications, which are similar to text message notifications; however, push notifications are generally faster and more reliable than text message notifications. To get the SubAssistant app, search "subassistant" on the Apple App Store or Google Play store. Once installed, sign into the app using your existing SubAssistant account.
