Concepts - Sketch, Design, Illustrate

By TopHatch, Inc.

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, PDF 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 and other in-app purchases:
- 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.
- PDF IMPORTS & EXPORTS. Maintain clarity, format, scale and style with standardized PDF docs, available as a separate in-app purchase.
- OBJECT LIBRARIES. For quick work, drag-and-drop pre-made or custom vector objects straight into your sketch. Vector object packs for architecture, landscaping, UI design, industrial design, auto design, fashion design, sketchnoting, visual thinking and more are available separately via the in-app store. Or, design your own and use them in-app or on iMessage.

If you’re not ready to go Pro, the basic app includes:

- UNLIMITED PROJECTS. Never, ever stop sketching.
- COPIC COLORS. The beautiful color wheel will make you say ‘wow’.

- GORGEOUS VECTOR BRUSHES. Pencil, Pens, Area Fills, Marker, Airbrush and Watercolor. All free.
- ADJUSTABLE PAPER with real-scale paper sizes, layout guides + rulers, transparency, graph paper and isometric grids.

What's New in Version 4.5.2

First off, we’re super excited about the new iPad Pros. The variable-refresh screen tech (up to 120Hz!), the extra memory and new 10.5” screen size… if you haven’t seen one in person head over to your local Apple dealer and have a look. So bright, so fast, so functional.

This update optimizes the layout on the 10.5” iPad Pro, and takes full advantage of the new ProMotion screen tech.

If you’re not an iPad Pro + Apple Pencil user, check out Wacom’s new Bamboo Sketch stylus, also now optimized for Concepts.

We’ll be back in a few short weeks with something amazing. Follow us on social media @ConceptsApp or send questions/comments to

Customer Reviews

A masterpiece!

This program is incredible! The best of its kind that I've seen so far. I am completely self-taught and a total rookie, and yet I can navigate through it. I can only imagine how powerful something like this would be in a professional's hands.
My ONLY complaint is that I have a hard time creating custom colors... I wish there were a more basic color wheel that allowed you to manipulate colors with a gradient vs. inputting actual numeric color values.
Still, one of my all time favorite apps. Thank you SO much!

Oh my Garsh!

I need an app to help show my daughter how to understand geometry. I had this free app laying in the back for about year and never used it since I bought my iPad Pro for my graphic design company.

Finally gave it a try cause I want graph paper background and there it was. Bought the pro version instantly. Then I started seeing all the functions this app offers. I am going to start using this in my company for sure now.


Great app, big fan

I just got an iPad for the first time and I am very pleased to have found this app. It works great with the pencil and has some really neat features that makes it ideal for sketch-thinkers such as myself. I love the ability (with the $8 pro upgrade) to move around parts of your drawings after you've made them, very handy!
