Focus on a narrow audience at first (Score 1)

I did not take a look at your app but IMO the 1st thing is having outstanding feature(s) that solve a concern encountered by people you know. Tell them you made an app that could interest them and then those ones will be able to give feedback. Listen carefully and try to attract them to your product... It may then be a snowball. Secondly, a website is a must have today. Show concisely your product, we must at first sight know what can offer your product. Make a beautiful website, an attractive one.
