Desktop, tablet, and phone. Autodesk has brought a feature filled vector drawing and layout application to the game.
I was pleasantly surprised the first time I saw InkPad for iOS as a vector editing and drawing application. It had most of the basic path and transformation and layering features needed for creating some pretty nice imagery and exporting. For its price, this is worth a look.

Then along came iDraw from Indeeo, which put a whole new level of ability, and an interface that made sense to access its capabilities. Autodesk purchased iDraw and rebranded/named it Graphic.

If you’re looking for the ability to create and edit your vector artwork, this app could make you happy, as it does for me. I have had good luck and enjoyed the use of Autodesk’s apps for iOS and believe their teams and marketing are putting together a fantastic suite of productive and creative apps.
Autodesk – Graphic on the App Store
Envosa – InkPad on the App Store (this app closely resembles the app first introduced by Steven Sprang who open-sourced the code to his app).
