The vector-based app Amadine provides everything you need for technical, artistic and interface drawing – without the steep learning curve.

The app is great for artwork that needs to be scaled to different sizes – whether a company logo or an illustration for a T-shirt and a billboard. Amadine also lets you quickly mock up web and mobile interfaces by producing multiple versions for various screen dimensions.

There are two main tools in Amadine: the Pen tool creates Bézier curve control points, with handles for adjusting them. (Bézier curves are the backbone of vector art, allowing for mathematically precise, aesthetically pleasing arcs.) The Draw tool lets you work free-form; the app automatically smooths your lines and drops in control points as needed.

Amadine has an array of other tools, including options for creating specific shapes like ellipses, arcs and stars. Use the Width tool to make lines feel more organic and natural by varying the width of your stroke at any point in the line. The app also offers rich controls for manipulating text.

And with its library of tutorial videos, you can learn all the ins and outs of the app in an afternoon – then get started on your vector-based masterpiece.
