First I wouldn't put ask_hn.htm on your main domain. Secondly, the app, while well polished, doesn't offer anything original. It looks like you sunk a big chunk of cash and resources into the design and engineering. You should've focused more on answering why you're doing what you're doing. You have an app. But what does it really do? Why would I use TaggTo? When would I use TaggTo? How does TaggTo make my life better? Does TaggTo offer me a way to express myself creatively? The biggest and most important question, do you have a community around TaggTo or the ability to build a community around it? I'd either pivot into something more community-driven or sink more funds into marketing.
