The service provides summaries to business books and reports. Very useful since business books tend to repeat ideas over and over. I dont give the app 5 stars because I keep getting signed out very often. If this is to validate I am still subscribed to the service the app should find another way to restrict access. At a minimum should have the option of logging in with Touch Id.
