How to cancel a subscription in the App Store
If you started a subscription to Llama Life from your iPhone, and would like to cancel this subscription, you'll be able to self-cancel following these steps:
Open AppStore app
Tap on your profile picture (top right)
Tap Payments and Subscriptions -> Subscriptions
Tap Llama Life, then tap Cancel
Note: the AppStore manages subscriptions directly so it needs to be done by you
