Hey everyone, creator here. This app has been a huge learning opportunity as far as app design and marketing goes. The app is fairly straightforward, but I spent far more time writing releases and emails, as well as examining and critiquing each different UI. I'm planning on writing a report in two weeks on the success or failure of my efforts, with detailed metrics on conversions, retention, and sales.
I'd love to answer any questions or address any feedback you might have.
