Startup Is Getting No Traction What Do I Do?

Hello I have an app I recently release called DzHaven. It is getting no traction at all. What do I need to do to get users and kick start this thing? Help much appreciated!

Why would a person seeking answers use your service as opposed to StackOverflow or specialized support forums where they can have their questions answered for free?

If you really want this to take off, you’d need to market it towards highly specialized and certified people. Also, an about page wouldn’t hurt. I’m not even entirely sure how your website works. If I set a bounty to $5, does that mean I have to pay $5 every time someone answers the question? Or does that mean that all the answers are blurry until I pick one and pay $5? 

What stops someone from giving lazy answers, or from using peoples’ solutions without paying the fee?
