No apology necessary. I'd probably react similarly if I felt that somebody was being unconstructively critical of an app that I created.

I was just frustrated, as you guessed, because I really care about the idea and the app, and I see so much promise there. I should have just said to the original poster that I didn't provide feedback because I didn't want to sign up for a second account, but my frustration made me get snarky, which I apologize for.

Thanks again to you and everybody else at Tricycle.
