Lesson for you:
Right way- “Hey, I’m working on an app to track expiration dates on documents, I’d like to hear feedback on what you guys think, and if it’s worth paying for… yadda yadda, etc”
Wrong way- basically everything you did. Pretending not to be the writer of the app, and then creating a new thread when the first one got moved where it belonged and trying harder to not be the app writer. Then this thread to try and find other avenues of free advertising for your app.
We’re sailors, we can smell BS a mile away. Honesty will get you a whole lot further, and might actually get you some helpful feedback. That and from what I’ve seen, an iPhone app might get you more traction on here than an android one.
