Introduce a Quick Starter Guide
Create a Quick Starter book resource for new users. Something that's quick to skim through to learn all the features and to use as a reference. Something like Steve Clark's guide (http://community.logos.com/forums/p/57421/409853.aspx#409853).
The interface is not intuitive, and while it could be imrpoved, I also understand that there is a lot of functionality and there is no way to make it all obvious to all users. These users need a guide.
Some users are going to be coming to the Logos mobile apps from being previous desktop users, some are coming from word of mouth, but I would think a lot are new users who are just searching the app store for a bible. There is little clue for those users as to how to use the app or to the amount of power available in the app. How many people install the app and turn around and immediately uninstall it because they can't figure it out? They need a guide.
Upon first installing the app, have it give the user a choice to begin using the app immediately or to open up the Android/iOS Quick Starter Guide (as a normal book resource that can also be opened at any time from the library).
Users need a guide to show them all the power that's available, so they will keep using the app and start spending money on more resources.
Normal usage is not obvious to many people. What indicator do they have that touching the little icon at the top left will open the Resource panel with Library, Search, News, Settings tabs? And if you don't touch it just right, if you touch just above the icon, along the top edge, you get something completely different (the jump-to overlay). This could be improved by adding indicators ("<<") to the left of the icon like the Play store. I would also suggest by default that that icon should be doubled in width & height along with the entire header row, including an option in settings to use the narrower, streamlined interface. I love economy of space in an interface and prefer the smaller header myself, but if you think about it as your reaching for that icon, if your honest, it feels like your in a closet trying to pick up a tiny crumb off the floor in the furthest corner. If you don't feel it, watch someone else and see if they don't squinch up their shoulders trying to reach that icon. It's not easy or obvious without a guide.
New users need a Quick Start Guide to show them basic use and to show them how to access all the powerful features in the app when they are ready. This is an easy add, low hanging fruit, with lots of benefits in training users, in keeping users who may then eventually start spending money.

Here is another common example of why a Quick Starter Guide is needed (among many):
People come to the Logos app from the app store. they have no idea what Logos is or how it works or what's needed for it to work. They need a guide, they need an easy to access and easy to understand store, and they need a low-cost base package designed specifically for mobile users.
