Confused with Free or Subscription

VOX’s has a nice audio product. I purchased the app for my iPhone for $5.99. I just discovered there is subscription fee of $15.99 a month, I believe it is for LOOP. However, I am not sure if my iTunes account will be charged or not for the App version. I liked the App so I gave the online trail too, this one I did not enter any credit card info so I do not think I will be charge, but plan to cancel my subscription to be safe. This is a good product, I just do not like the pricing structure. I have an email asking about the App fee. I will update this post when I am given a response.
