Difference between Anytune Pro & Anytune Pro+

There is no difference.  Anytune Pro+ and Anytune Pro are functionally identical.  

Originally Anytune Pro was a middle version in the portfolio; before in-app purchases existed.  Anytune Pro continues to exist to enable us a way to provide existing owners updates. 

We would like to remove Anytune Pro from the App Store, but then we would not be able to deliver fixes to our existing users. 

We are committed to providing support and updates for our Anytune Pro customers.

We do encourage new customers to go with  Anytune Pro+.
