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!
