Today's Good Free App of the day illustrates perfectly why developers working on drawing apps need to come up with a unique or exceptional proposition in order to generate interest in their app. There are so many art apps that are inexpensive or, like this one, free (Drawing Carl is, however, only free for a limited time.)
In this app you can import your photographs and "improve" them with designs of your own making, create scenes with Carl and his friends or just use the pencil, marker, stamps and other features for free drawing fun! Two words of caution - there is an in-app purchase for 99 cents but it's not obvious and all the features of the app are available for free. Secondly, the drawings can be shared directly with Facebook which may concern parents for privacy reasons.
