"I use Concepts more than any other tool. I absolutely love it. The natural, fluid, vector-based workflow is so easy to use, but incredibly powerful. The technology never gets in the way of creativity. The fast and clean user experience makes it a joy to use.” - Yarrow Cheney, film director

"The Concepts app has not changed what I do, just transformed how I do it. It offers me the power, flexibility and adaptability of technology with all the sensitivity and immediacy of traditional hand drawing. In short, it is an app that I now cannot imagine being without, and the only time I’ve experienced something that betters pen and paper.” - Ewen Miller, Calderpeel Architects

Unreasonably fantastic

I’ve been using Concepts for years now, during which time it’s evolved from “oh, that’s nice” to an absolutely essential part of my workflow. My main use of Concepts is for various kinds of technical sketching/drafting purposes. Everything from concept drawings for projects destined for the workshop and/or CAD, pattern drafting complex fiber arts work, and much more. I’m not a production visual artist; rather Concepts is my first-stop design studio. As such, Concepts’ infinite canvas, layers, and vector-vs-pixel based model are the key features that make my work a joy. With the infinite canvas, I can seamlessly work and sketch on related ideas & drawings, then rearrange and/or export what I need for inclusion in other documents. Layers are a gigantic timesaver, making it easy to select, duplicate, and modify various “slices” of my work, allowing easy correction of mistakes, evolution of ideas, and eliminating lots of tedious redrawing. Likewise, the vector model plays into the layer support, making it straightforward to select, group, and edit individual artifacts. All that’s the tip of the iceberg. As you get further into it, so many features come together to make your work better and faster. How about a *tiny* bit of smoothing to clean up my janky line work? Or crank smoothing to 100% for minute to get ruler-straight lines without even having to break out the “Precision” tools.

The infinite canvas is what I needed

Since I bought my iPad a few years ago, I have been somewhat disappointed with the note-taking apps I have tried. I had a hard time finding things I had written or drawn. My notes would be broken into files or pages. One app had an “infinite” solution, but it just meant scrolling horizontally for a long time trying to find something I had written.

The infinite canvas that Concepts offers solves that problem for me. I can unload massive amounts of notes and sketches into a single sheet. With a few gestures, I can see everything at a glance, and then easily zoom in and find what I need. Not only am I finding what I have already written, but the drawing tools make it easy to refine and polish the messy jumble of notes I started with. It seems simple enough, but Concepts is the first app that I’ve tried that has been successful with this function.

The only feature that is missing for me is the ability to sync files between devices. I don’t really plan on making notes on my phone, but it would be nice to see things I’ve done on my iPad, even if it is Read-Only. That said, the infinite canvas is a game changer for me. It suits the way my brain works very well. I feel like I’m finally able to organize myself and move forward on some of my projects.

It’s missing so many features

There are good things I can say about this app and not so great things. I love the versatility, the ability to upload photos, images and the ability to create color palette. I really love the ability to take colors from other places to create color palette. I hate that there is no rainbow graduation wheel to choose color from. If you don’t like their color choices, you have to go find an image with the color palette you want, upload them, create your palette and then get rid of the images if you don’t want them and a lot of the time artists already know exactly what shade they are after and just want to go to a wheel and choose. This is time consuming and time is money. I hate that there is no “snap” option for guidelines or shapes to lock onto grid lines or to lines on your work and if your tool or fingers move even the tiniest bit, they get knocked out of place and it really makes any kind of precision work or work impossible. You really can’t line anything up to make a perfectly straight line. When you change the composition of a shape by moving out the corners, any other shape you choose will hold that new composition. Also not desirable. It doesn’t snap back into shape. You have to painstakingly reshape it by hand and hope you get it right. When you are don’t using a shape tool, it doesn’t recover its original shape. Honestly this thing is so many headaches that I am looking for other options.
