For iOS:

Find the latest instructions for unsubscribing on Apple’s website here https://support.apple.com/en-us/HT202039#subscriptions.

  4. Tap Subscriptions.
  5. Tap the subscription that you want to manage.
    If you don’t see a subscription but are still being charged, make sure that you’re signed in with the correct Apple ID. If so, you might have subscribed directly with the provider and not through iTunes. In this case, contact the content publisher or app developer directly to cancel your subscription.
  6. Use the options to manage your subscription. You can choose a different subscription offering, or tap Cancel Subscription to cancel your subscription. If you cancel, your subscription will stop at the end of the current billing cycle.
