If you are a developer of Android apps, you probably want to layout your UI on paper before you start to build it. Doing the UI can be a pain if you have to freehand I would think.
A new stencil kit for Android UI design has surfaced from UI Stencils that sells for $24.95. With the kit, you get a stencil with all the shapes and buttons you need to lay out your Android app UI.
You get the stencil, Zebra mechanical pencil, and two sets of UI stencil stickers. Using the kit, you are ready to design away.
