Create a screen by screen by screen FAQ on how to use this great app.
After about three paragraphs, your "Getting Started Guide" seems to be just a series of answered questions.
I watched your advertisement video. It's a nicely made ad. But for being a step by step tutorial, it's like watching a car commercial to learn how to drive a car.
I can tell you put a lot of work into this program. But figuring this out is like playing a "seek and find" video game. Why are you making us work so hard just to use this?
So my suggestion is that you spend an afternoon, do a screen capture of the various screens and create a single page for this website that has all the screens with a full description of what its and an explaination of the buttons.
...and just as important... keep the guide updated for when you update the app.
IN ADDITION, a simple "icon guide" table would be nice.
