In the wake of several apps abusing subscriptions, Charles Arthur put together a well-illustrated guide to finding the app subscriptions management screen on iOS. It isn’t in the App Store, nor can you search for it in Settings because it’s inside of a web view. Ryan Jones previously registered a single-serving domain that redirected to the subscription management screen, but Apple legal didn’t like that.
This needs to be easier. Subscriptions are an increasingly-relevant revenue model. It has been two years since Apple revised the terms of subscriptions to make them more developer-friendly, but the management UI for users has simply never been easily-found.
