It's my word against his, I'm the developer, I know what I'm making. I have no problem in him not believing me. The problem is disbelief and then commenting on it, which is fruitless as I'm not in a position to preview my app to the public, nor is he in any position to comment on an application he hasn't seen or used. Take my experience for what it's worth, if it's worth nothing then skip me.
