A common request is the ability to see what titles are available for use on the iPhone and iPad. Here is what we have to help you. Also, please remember that in order to view a resource in the iPhone or iPad app, you must own a Logos 4 base package and the title you want to access.
Complete List of Available Titles:
We now have a complete text list of all the titles currently enabled for viewing on the iPhone and iPad. This page is updated weekly. http://www.logos.com/iphone/support/resourcelist
Product Pages:
When you do a search for a product on Logos.com, if the resource is enabled for viewing on the IPhone and iPad applications, it will display the iPhone enabled badge like the one below.

Faceted Browsing:
Our web development team is currently working to deliver faceted browsing on Logos.com. This means that you will have the ability to browse and search through Logos.com and filter your results to only show iPhone/iPad enabled resources. This feature is part of a larger project that involves some major overhauls to both the front and back end of our website. At this time, we don't have an ETA on when the functionality will be released, but we wanted to let you know that we have heard your requests and are working to deliver them as soon as possible.
