TapZilla is a Y Combinator-backed company that launched October 13, 2010 and is taking the daily deal model and applying it to discounts on paid mobile apps. Through TapZilla.com and AppRebates.com, the company has given out more than 25,000 paid applications to its users and has pioneered the method of connecting developers with users by giving away paid applications for free. TapZilla has been featured by TechCrunch and Forbes. Each day, TapZilla features a paid iOS app. To get the deal, the user clicks on the “get App Now” button, which will then prompt TapZilla to ask for your email. Users receive an email with a link to the app in the App Store where they can purchase the app and a coupon code. Once the app is purchased and downloaded, users are prompted to enter the coupon code once inside the App’s interface. The app can also be prompted by shaking the phone. Once the code is entered, TapZilla automatically puts the app cost in the buyer’s PayPal account or can issue an iTunes gift card.
