So one feature I always wished I had for the iphone/ipad was the "read aloud" option.  Well there is but it is built into the iPhone/iPad settings.  Here is how to use it with your Logo app:
1.  Go to Settings/General/Accessibility/Speech
2.  Enable "Speak Screen"
3.  Open Logos app to book you want to have read to you
4.  swipe down from the top of the screen with 2 fingers.  
*You can adjust the speed, etc.  
**Make sure your menu isn't in view otherwise it will read it too
***It will actually turn the page for you and everything.
I was very excited to see this work.  Let me know if you find this useful.
