Autodesk has a fantastic record of powerful, well-built apps. Continuing the pattern, the Pixlr Express makers today released SketchBook Ink, a (you guessed it) sketching and line work app specifically built for tablets 7" and above.

While SketchBook Ink is perhaps not up to handling a professional illustrator's full time workflow, it's a versatile tool with functionality that's suprisingly sophisticated for a mobile app. Ink's got a full screen workspace built on a "new resolution independent engine," with seven preset ink styles, a wonderful color picker (with RGB sliders, a color wheel, and a block for shade selection), layering options, and plenty of options to explore. Users can even get rid of all the clutter using the small center ring also present in SketchBook Pro.

While SketchBook Ink appears very similar to SketchBook Pro at first blush, Ink is more focused, offering functionality specifically tailored to those creating line work, and allows for much larger exports.

So far during my time with the app on the Nexus 10, everything has been extremely quick, responsive, and accurate. Drawn lines render instantly and are perfectly smooth. Though I don't do too much digital drawing or painting, the app is an absolute pleasure.

Once you're done drawing, you can export your image in up to 12.6MP PNG format either to your photo library (or send via email) or export to a PNG up to a dizzying 101.5MP to your Dropbox account.

If you're giddy about the idea of a great Autodesk app with a pleasing, well-made interface that provides almost everything you could want in a mobile sketching solution, the only thing standing between you and SketchBook Ink is a $4.99 payment and the click of a button.
