I want to subscribe to Susan’s new app, but when I go to the iTune’s Apple App Store (Lifestyle) I see only the free app. How can I subscribe?

Once you get the free app, you can subscribe inside the app. You will see a button “Subscription Details” under your short free daily forecast. When you press that button, a menu of prices will come up for you to choose, depending on how long you want your subscription to be.
