There's a lot of ways to answer that.

First, I'd want to know what other businesses you're marketing it toward and/or have embraced the app. I sell analog games (board games, role playing, etc), meaning I like to make sure I associate the store with positive family friendly experiences. 

I'm also not a huge fan of our local Chambers of Commerce, so I'd never find the app through that or become a part of it through that particular business.

So the answer is: Yes, I'd consider it, but free doesn't always mean relevant or good for my business.
