I have an android so I can't download the app. Looking over the linked page and your website, here is my initial read:
1) I need this stuff on the web. I spend most of the day on my PC and if I'm doing freelance stuff I need emails when new things pop up and pc (preferably web based) access.
2) WAY to generic. Yelp started with restaurants, salesforce.com started with sales people. Both built generic tools that transcended the needs of those narrow verticals,but did something that IMO you have to do. Define your target user and build something they will love. Network Effect matters a ton with this kind of app and without tight focus and tight marketing you will never get it.
