AppsFunder is a crowdfunding-site 100% focused on the mobile app - business. Developers can receive pledges for developing new apps for Android, Apple iOS. Backers make money from the sales on Android Market and iTunes when the app is published.
AppsFunder is the perfect solution that a developer needs to gain recognition and trust in a competitive industry where applications are being tested, rejected and launched on a daily basis. The benefit also spreads over to those that support applications since they too will be making profit on the "apptions" that they buy.
