Here's mine: http://www.fiestastic.com
NOTE: It's now in private beta, but if you (this goes both to the Crowdspottr team as well as anyone reading this :P) would like to give it a try, just sent me an email to manuel@fiestastic.com with a link to your Facebook profile and I'll add it to the list of "allowed users".
I've taken more of a regular website approach while you guys are doing first a mobile app/site, which makes more sense, but I'm not very skilled in native iPhone/Android development.
I'm not sure if I should be depressed (someone else is doing what I'm doing, and so far, looks better!) or happy (someone else is doing what I'm doing, so must be something worth doing!), but anyway, good luck with Crowdspottr! I'll be keeping an eye on you ;-)
