iDraw for iPad review
iDraw is a vector-based tool, meaning it will transform your designs into mathematical equations so that no matter how big or small they become, they will always remain sharp and unpixelated. Freeform works in a similar way, but iDraw offers many more options. For instance, a text tool is already implemented.
You can easily create different shapes, fill them in with a single colour or a gradient, apply a shadow to them, alter the size, type and colour of the line, and so on. iDraw allows you to work with up to 10 layers and create as big a canvas as you need, whereas most other programs limit you to the iPad’s own size.
As with other programs, there are many options for exporting work, including PDF and SVG (the latter lets you easily alter your work further in a program like Adobe Illustrator).
