Square Register Supported Integrations
While you can’t download and run third-party apps directly onto Square Register, if you use an integration with third-party apps you can still access all your data from your online Square Dashboard.
Square Register and Retail
If you are using the Square for Retail app on Square Register, you’ll have access to both the in-app features and a full suite of features on your Square Dashboard. Note: The Square Retail App is supported on iPads running iOS 12.0 or higher and Square Register.
Square Register and Restaurants
If you are using the Square for Restaurants app on Square Register, you'll have access to Square for Restaurants Free features on Register.
