Open iTunes to buy and download apps.


Concepts is the digital design sketchbook of the future. It’s powerful, flexible and smart, so you can go from quick sketches to beautiful and precise illustrations in a single app. Concepts is made for iPhone, iPad and iPad Pro w/ Apple Pencil so your sketchbook is always ready. Enhance your creative capabilities with our infinite canvas, flexible multi-touch shape guides, completely adjustable vector strokes, and the ability to export in powerful formats like SVG or CAD. Once you learn to use Concepts, you’ll never want another sketchbook again.

Concepts is one of the top-rated design apps in the App Store and it keeps getting better. It has been used to design a new hospital, build a yacht, craft award-winning quilts and create fine art featured in galleries... Concepts really shines when you’re conceptualizing ideas, rapidly prototyping, or drafting quick visual iterations.

Unlock the full power of Concepts with the Pro Pack:
- PRECISION TOOLS. Bring the power of CAD to your sketches, through multi-touch shape guides, automatic measurements and snap-to sketching. We’ll do the math for you.
- ADJUST ANYTHING. Tap-and-hold any stroke or group to move, stretch, smooth, copy, delete, or change ink weight and color.
- INFINITE LAYERS. Seriously. View them without losing context.
- POWERFUL EXPORTS. Send high-resolution (300dpi+) PNG, vector (SVG), CAD (DXF), Adobe Photoshop (PSD), and standard formats anywhere.

If you’re not ready to go Pro, the basic app includes:
- ELEGANT, CLEAN INTERFACE. We get out of the way, so you can focus on your work.
- INFINITE CANVAS, SHARP ZOOM & ROTATION. Also Portrait and Split View Multi-tasking.
- 5 LAYERS with intelligent separation.
- IMPORT IMAGES. Learn by tracing, or mark up images with notes to give feedback to coworkers.
- UNLIMITED PROJECTS. Never, ever stop sketching.
- COPIC COLORS. The beautiful color wheel will make you say ‘wow’.
- BLUETOOTH STYLUS SUPPORT. Connect your favorite stylus from Apple, FiftyThree, Adobe, Adonit, HEX3, Pogo or Wacom. Includes Palm Rejection. Full support for Apple Pencil on iPad Pro.
- GORGEOUS VECTOR BRUSHES. Pencil, Pens, Area Fills, Marker and Airbrush. All free.
- ADJUSTABLE PAPER with real-scale paper sizes, layout guides + rulers, transparency, graph paper and isometric grids.

If you love to sketch, then Concepts is for you. It is the favorite app of Professional Designers, Illustrators, Architects, Industrial Designers and Makers everywhere. It’s perfect for architecture, illustration, organic CAD (DXF) and vector (SVG) shapes, a simple sketch or sketchnote, even layered PSDs!

What's New in Version 4.1.3

As a designer, you know feedback is critical to the design cycle. Your feedback directly affects our work, and as a result, today you can enjoy:

IPAD PRO 9.7”. Show settings panel for Apple Pencil and enable pressure response.
LEFTIE SUPPORT. Now you can flip the interface so you don’t keep hitting that infernal settings button. Hooray!
IMPROVED GALLERY THUMBS. If galleries had thumbs, they would now be able to stretch out to their full glory. Ours do.
PORTUGUESE. Por que usar o Inglês, quando o idioma é melhor?
HIGHER RES EXPORTS on iPad Pro. Up to 4X the screen size, or a massive 10928 x 8192 on the 12.9” device, or 8192 x 6144 on the new 9.7” iPad Pro. Careful, that’s sharp.
EXPORT TO ICLOUD and other cloud providers. Very useful.
PIN THE TOOLBAR. Hold your ground, toolbar. Not everyone likes it when you run away during intense creative sessions. (Hint: Find me in Settings.)
CHANGE THE BACKGROUND color multiple times without the color wheel disappearing. Tap elsewhere to dismiss.
GET PROPERLY THANKED when you purchase the Pro Pack. Which you should definitely do if you haven’t already. If you have, thank you again.
SOME OTHER BUGS around copy/paste and object linking, etc. All sorted.

As always, you can find us on Facebook/Twitter/Instagram/Pinterest/Medium/YouTube/YouKu. Just look for @ConceptsApp. We’d love to see - and share - your work!

Also, if it’s not too much trouble, we’d love your updated five-star reviews. They’re very helpful and very motivating. We’ll be back with more in a few short weeks.

Happy Creating!
