AppSketcher，谈不上是为iOS程序员设计专用的APP，应该说是一款涂鸦软件，给你一个iPhone的框架(横的、竖的都有)，为你的作品先制作一个简单的构图，内置了简单的范本、颜色笔等，支持Dropbox或储存在相簿中。

官方说明：

Do you have the next great app idea? They say that the best way to start designing an app is to use a pen and paper…and we agree. But what if you want to use your iPad instead? If the iPad is your tool, then AppSketcher is your app!

‘AppSketcher’ is a very simple yet functional iPad app that is used by anyone looking to create their own apps. Our app gives you the feeling of pen and paper, but on your iPad. Use AppSketcher to ‘mockup’ or ‘wireframe’ your next
great app. Once you are done, you can share your design with your developer, team, or friends.

Features:

- Very simple to use! Just like Pen & Paper!

- Several templates available
- Several ink colors and styles
- Share your designs via Email
