Cancel an app in the free trial period on iPhone
I set up an app with a free trial period and have decided to cancel the app. How do I do that?
iPad Air 3, iPadOS 18
For free trials started with an in-app purchase, cancel those here:
View or cancel app subscriptions on iPhone - Apple Support
If you started the free trial with the developer directly, then those are not managed by Apple and you would need to cancel on the website where it was started. It may help to know where the free trial was started and what it was for.
