Show HN: my new site helps iOS devs share, track and promote promo codes

iOS promo codes are in theory a great way to get people to try and talk about your app, but I found it's really hard to get the most of them. I could tweet a couple of codes, but it's a complicated multi-step process to redeem them. Once I've sent them, I've no way of knowing if the codes have actually been used or not.<p>I built http://pcod.es/ to make it easier. You paste in some promo codes along with details of your app, and get a short url (like http://pcod.es/pi6) to share. The site tracks which promo codes have been redeemed so it's much easier to make sure you get the maximum exposure for your app. Finally, if users choose to sign up with Facebook and enable the option, a link to your app appears in their feed.<p>I'd love some feedback!
