In August, 2018, Apple removed the Freedom version 3.0 app from the App Store. But if you've previously downloaded Freedom, you can get it back.
Follow Apple's instructions for App re-download here.
Freedom is working normally, and your app will work the same as before when you re-download. Freedom works on iOS 12.
Our new Freedom v4.0 app is available in the app store. Please note Freedom 4.0 is currently limited by Apple to blocking websites in Safari.
