Start with prototyping Today!

I couldn’t believe that there is no complete free mockup app out there. And I was right. After wasting a lot of time with searching I found one, which fulfilled all my dreams <3: Pencil

Why I love it:
– Easy to use
– All relevant shapes for Desktop GUI, Web, IPhone, etc
– Open source
