Question
I am a young entrepreneur and developer. I released my app a month ago and believe I have a good product for an audience I know exists. However, I am strapped for cash and am struggling to get traction. Any help, tips, experience, suggestions and opinions would be greatly appreciated.
Answer
There's a lot of ways you can do this.
You didn't mention what kind of app it is and what operating system it runs on. This could yield some specific ways of marketing.
If your app is sold on itunes, consider contacting the yahoo writer who releases "free today apps" on their columns.
