Stop auto renewal on apps

You will have some options to get this done. Please try the following one at a time:

1. Open Settings ➔ Apple ID (Your Name at Top) ➔ Subscriptions: You can manage your subscriptions here
2. If the above does not show your subscriptions or you are not able to manage it, then Please start here ➔ Refunds, Subscriptions & Billing Questions
3. Double check the subscribed App's settings to check whether the subscription can be cancelled from there.
