Ask HN: How to Conduct a User Survey for a New App

I want to spend about $5-10 per person, to have my user demographic download the app and basically tell what worked and what needs work.

Posting on Fiverr lead to a couple responses but none are in the target demographic. So I tried Craigslist but they suspended my account without giving a reason. I'm appealing the suspension but haven't received any response yet.

Reddit might work but my concern is that it would get flagged as it did on Craigslist.

If someone has any experience conducting user surveys for apps I'd appreciate some tips.

Thanks!
