Show HN: Craigslist housing maps on iPhone

I've been running cribq.com for 5 years now. I move a lot so I use it a lot. :)

The iPhone app is finally something I'm proud of. You can see all the Craigslist listings on a map, favorite them, take notes, zoom into neighborhoods, email with a custom template, and more.

I'm struggling with marketing, which is where I would really like some suggestions - right now usage is pretty good but I'm shooting for much more.

Thanks!

Some reviews from the appstore:

"A complete game-changer. Completely simplifies the Craigslist housing search."

"This is the best way I know to search for an apartment by location, narrowed down to neighborhood or block!"

"This app is def a time saver!!! It's now my # 1 most used app :) Thank you for making my transition from Southern Cali to Chicago an easier one!!!"

"Very, very helpful. It's the perfect apartment search app on the go. Wherever, whenever... :)"
