Concepts: Smarter Sketching, Design & CAD for Architecture & Illustration

By TopHatch

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 iterate on everyday doodles, create beautiful works of art or precise technical illustrations. Concepts is unique because of its 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 to leave your iPad at home.

In September 2015, Concepts became the top-rated design app in the App Store, and it keeps getting better. It is so powerful it’s been used to build a hospital, design a yacht, craft an award-winning quilt, and make custom greeting cards that are taking Spain by storm. Concepts really shines when you’re conceptualizing ideas, rapidly prototyping, or producing 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 to move, stretch, smooth, copy, delete, or change ink weight and color.
- IMPORT IMAGES. Learn by tracing, or mark up images with notes to give feedback to coworkers.
- 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.
- 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.
- 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!

The Perfect App For The Apple Pencil

Although this app does not feature pressure sensitivity with the Apple Pencil it is far more point accurate than Sketchbook and more user friendly than Procreate and Adobe Photoshop Sketch. If you are a new user to the Apple Pencil this app is for you. Its color wheel uses Copic colors but you can adjust the colors from there to whatever you would like. It provides everything that Procreate, Photoshop Sketch, and Sketchbook offer but cheaper and again - EASIER to use. I hope in later updates they come out with this app in compatibility with the Apple Pencil sensitivity. The thing that swept me over the edge with this app is the point precision with the Apple Pencil point. There was virtually no lag and where you lay the point of the pencil is where the point begins. I found this to be a major issue with the other apps listed. I really love this app and will using it ALOT!

I have an Apple pencil!!! Best drawing app

This is hands down the best drawing app for the apple pencil, 100% pin point accuracy, the lines start at the tip of the pencil. Other major apps have major flaws. This is the best app, also when you zoom into your art work it stays super high resolution unlike others that look like a blob of small pixels like 1980's Mario. This app is very very impressive, the only app I use to showcase my apple pencil and iPad pro, thank you

Master of Lines

It has taken me a while to warm up to Concepts—it operates in a very different way than I am used to, but these last few updates definitely seal the deal. The tutorials are super (although The pace of some of them is too fast for this feeble old timer)! Please keep them coming for a while. Can't wait to use on the Pro.
