Handy Art Reference Tool is an innovative reference app designed specifically for artists. This powerful tool provides rotatable 3D models of hands, feet, skulls, and head busts that can be easily manipulated for drawing and painting references. The app's intuitive interface allows users to adjust lighting with a 3-point system and customize poses for different body parts.

One of the standout features is its collection of over 10 animal skull models available through an additional pack, making it perfect for anatomical studies and creature design. With the recent update to version 5, artists can now modify model materials by adjusting textures, specularity, and colors. This versatile app caters to various artistic needs, from professional comic book creation to casual sketching.

The app particularly benefits artists who work on character designs or portraits. Instead of struggling with awkward poses in front of a mirror, users can simply rotate and adjust virtual models to capture the perfect angle and lighting. This functionality saves valuable time during the creative process while offering precise references that might be challenging to achieve otherwise.

Handy Art Reference Tool offers several distinctive features that set it apart from other art reference apps. First, its comprehensive library includes multiple 3D models of hands, feet, skulls, and head busts, each with customizable poses. Artists can create and save their own unique positions, providing endless possibilities for reference work.

A notable feature is the advanced 3-point lighting system. Users can precisely control light sources to study how shadows fall on different facial structures from various angles. This capability proves invaluable when working on realistic portraits or detailed illustrations where accurate lighting is crucial.

The recently added material editing function in version 5 enhances the app's versatility. Artists can now experiment with surface properties, turning off textures or applying color tints to models. While some features like foot rigs and animal skulls require additional purchases, the core functionality remains robust and useful for most artistic projects.
