AppAdvice has once again teamed up with Hesham Wahba in order to offer you a chance to win one of 10 promo codes for Tracing Paper ($2.99) for iPad, iPhone, and iPod touch.

Just like different sets of physical art tools, there are many types of art apps for the various needs of the artist. One of those tools is tracing paper, as in both the physical product and this nifty app by Hesham Wahba.

Tracing paper is a semi-transparent sheet in which you can see a background image for guidance. It can be used for anything from copying the image exactly to using it as just an outline, such as the form of a person but you change the facial expression, clothing, etc.

With the Tracing Paper app, you have a tidy package that’s always ready whenever and wherever you are. In addition to the transparent paper overlay feature, the app includes a resizable pencil and eraser, paint bucket, optional adjustable alignment grid, 12 step undo and redo ability, multiple project support, auto-saving, and a handful of import and export options.

Tracing Paper can be fun and useful for kids or serious artists, and could offer even more potential when paired with a touchscreen stylus.
