delete an app so im not charged

Deleting the app will not prevent a recurring charge. You can delete the app as you would any other application, hold your finger over the app icon until they start to wiggle and then tap on the ✖ to delete it.

To prevent the recurring subscription charge, see this support document. View, change, or cancel your subscriptions - Apple Support

You need to cancel the subscription. Just deleting an app won't stop charges. See: View, change, or cancel your subscriptions - Apple Support
