AppSeed is a new mobile application development platform that makes it easy to turn paper plans into working beta apps. The platform allows you to turn a drawing of an app into an actual app in no time flat. All you need to do is sketch out your app, ensuring that enclosed spaces are clearly marked, and voila! AppSeed will use your rough sketch as a template and let you add everything from maps to text boxes.
Once you've tinkered with your app, you can share it with friends and teammates (the shared app is an HTML5 app) for testing and refinement. You can even connect to Photoshop to help spruce up the look of your app. AppSeed has been successfully funded on Kickstarter and can be yours for only an $8 pledge.
