If you see the message "This application requires iOS 13.0 or later" when attempting to download the Purezone app, this is an indication that you must update to iOS 13.0 in order to download and use the Purezone Application.

Note:  Older iPhones, such as the iPhone 5, iPhone 6 and others are not capable of upgrading to iOS 13.0.  To use the Purezone app, you would have to purchase a newer iPhone.
