Hey HN,

I have a free app out on the App Store and I'd like for a lot of users to try it out to get an idea of whether they like it or not and give me some feedback. At this stage even just a couple of hundred users would be good enough to give me a decent idea of whether I'm headed in the right direction. What are some creative, lean ways of getting people to try my app?

I'm going to write about it online on a few forums that might have users interested in the specific subject, raise awareness. I could pay for Google AdWords, but that will probably cost me quite it bit for the % of people who will actually end up downloading it. I'd certainly prefer not to have to pay for it! Meetups for that specific domain are an option, but they do tend to have a very small return for one's time investment, probably just as effective as spending a couple of bucks on AdWords. App Store SEO is a given, so I won't even go into it.

What are some other neat creative techniques I could use? Are there any truly reputable resources out there for guerrilla marketing techniques? There are a TON of books on the subject, don't even know which one to start with! Would appreciate some direction.

Thanks!
