What's New


* Palm Rejection! Using any supported bluetooth stylus, you can now rest your hand on screen. **Be sure to disable “Multitasking Gestures” in the iPad Settings app before using.
* Pencil by 53. Pencil is a well-balanced carpenter's pencil with an eraser on the back side. Once connected, rest your hand on the screen to draw, then flip it around and make corrections without touching a button. It's a wonderful experience. (Of course, we still recommend you long-press your lines to adjust them. Why waste a perfectly good line?) If you don't have a Pencil, tap the link in-app and check it out.
* Change the pressure sensitivity and hand position for ultimate stylus control.
* Improvements across all styli. Notably, line-waviness in Adonit and Adobe styli has been fixed, and every stylus feels more responsive.

Don't have a stylus? See our recommendations in the Manual, or in the new Settings screen in-app.


* Smoothing Presets. Set smoothing on any tool before you draw, and lines will sharpen up after-the-fact.
* New Settings Interface adds custom paper sizes, paper rotation, and unit locking.
* Improved Performance to the tune of 25%.
* Creative Cloud Market is back! Adobe has graciously provided thousands of free assets that you can use in your project. Creative Cloud account required.
* Fixed a number of bugs including image opacity and the broken eraser.

App Description

Concepts combines the precision of technical drawing with the elegance and style of artistic sketching. Use an infinite canvas, flexible multi-touch shape guides, after-the-fact stroke adjustments, and powerful export options to bring all your ideas to life. It's the smartest, most flexible sketchbook ever.

Precision Mode brings the power of CAD to your sketches. Use flexible multi-touch Shape Guides for creating perfect lines, arcs, angles, ellipses, and rectangles; perfect for layout and perspective, creating structure, and anything you'd use a ruler for. Snap-to Sketching - like auto-complete for drawing - enhances your accuracy, while Scale and Measurement do the math for you.

Your ink never dries. Select individual strokes or groups with a long-press, then move, stretch, straighten, or change the ink weight and color. Create objects and make copies. Delete individual strokes. Enjoy infinite layers. Concepts is designed for exploration and real-world translation of ideas.

Use your favorite Bluetooth Stylus from FiftyThree, Adobe, Adonit, HEX3, Pogo, and Wacom. Export your work to dozens of professional applications for further use or send via email, web link, open-in, and cloud solutions like Dropbox and Adobe Creative Cloud. Concepts exports high-resolution (300dpi+) PNG, vector (SVG), CAD (DXF), Adobe Photoshop (PSD), and standard formats.

An interface that melts away. An infinite canvas with sharp zoom and rotation, gorgeous vector brushes with COPIC colors, amazing stylus support, real-scale paper size guides, layout guides and rulers, transparency, graph paper and isometric grids, and unlimited layers. Import images from anywhere for tracing or add text labels. Sketch and design to your heart's content.

• Architects, Engineers, Surveyors, and Landscape Designers - enjoy technical precision of shape guides, snap, scaled measurement, and 300dpi+ printable output options + Adobe PSD.
• Product Designers, Makers and Illustrators - sketch with natural vector brushes, tweak at stroke level, then export to SVG or DXF for laser cutting, rapid prototyping and vector workflow.
