Concepts: Sketch, Design, Illustrate & Architect

By TopHatch

Open iTunes to buy and download apps.


The future of professional design is here: Concepts intelligently combines paper + pencil with powerful vector manipulation. Make quick sketches, beautiful illustrations, and precise drawings with ease and style.

You’ll love the infinite canvas and layers, flexible multi-touch shape guides, vector manipulation with advanced transforms, and the ability to export your sketches to powerful standardized formats like SVG, PSD and CAD (DXF). Concepts sets the standard for productivity in the mobile era.

Concepts saves you time and enhances your creative capability. Use simple gestures like a tap-and-hold to select anything, and configurable shortcuts for unlimited undo, making adjustments, and accessing layers or the iconic COPIC Color wheel.

Concepts is optimized for the iPad Pro with Apple Pencil, and works brilliantly on iPad and iPhone so your sketchbook is always with you.

With our unique approach to precision sketching, amazing Architects, Illustrators, Professional Designers and Makers like you have designed hospitals and boats, landscapes, illustrations and game art, outlined major film storyboards, even crafted award-winning quilts, greeting cards, furniture, robots and drones!

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.
- ADVANCED TRANSFORMS. Distort, Perspective Warp and Skew. Concepts is the only app on iOS that provides the full desktop-class set, and does so with an incredibly simple interface.
- 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 sketch 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’.
