Is it an accepted behavior on HN to repost a url, say once a week?

I'm a junior developer and just launched my first android app on google play. It's kind of technical (i think) and i was hoping people here, being more technically inclined, would be willing to try it out and help me "reach for the stars" :) I know it says "begging for promotion" all over my face but please don't scorn me for trying. At least tell me whether it's ok to repost, and how often. Thanks.
