Customer Reviews

Perhaps the best creative tool that I have ever purchased

I have been a graphic designer and a programmer for 30+ years and this is one of the most amazing creative tools that I have ever used.

When I first purchased my iPad Pro and Apple Pencil I spent weeks trying all of the drawing and note taking apps that I could find. After a few days ‘Concepts' quickly became my favorite choice for drawing, taking notes, and sketching out ideas.

This app has a ton of awesome features. Here are some of my favorites:

• resolution independent brush strokes that I can change the appearance of at any time
• the animated color picker (yes, it’s that awesome)
• the double tap and triple tap shortcuts to undo/redo
• layers that I can easily hide, rearrange, delete or merge
• the ability to export to Adobe Illustrator and Photoshop
• in-app text chat with developer for tech support (wow…really helpful)

You can tell that developers have put a lot of effort into this application. It has an elegant interface that is both beautiful and intuitive. They have also compiled an awesome library of interactive tutorials and training movies that are accessible from within the app…along with an detailed user manual.

I highly recommend this app. Get the Pro Pack bundle…you won’t regret it.

Love it and I have a suggestion for a good tool

I love the concepts app, I have tried many other drawing related apps and this is a very wonderful one. Drawing on this one is smooth and rather detailed which is at the top of my list for the best graphic presentation even when exporting the art files. I have one suggestion though that I thing would make this an even more enjoyable app and that is if you would maybe make a blurring tool. The tool would allow artists to smooth out and merge colors giving the art piece a fine gradient of color, this would even be good with shadows and light on surfaces drawn for dark forming out to lighter apposing colors. That's all I would suggest, the app is lovely and I think it is wonderful as it is and thought maybe putting that idea out there may give you creators something to ponder, keep up the great job.

Well pleased indeed!

After cycling through the Adobe CC Mobile apps and some other drawing/sketch titles I found myself just disappointed. Even with the limitations of my first gen iPad mini this app works quite well. I believe that the creators put great thought and effort into this title. I have been using Concepts for only a day now and I find the overall accuracy of using the Adobe Ink pleasing. I was once thinking that something was wrong with my iPad as I was not finding the accuracy I was wanting with the other apps that the Ink was designed for. That frustration is a thing of the past. From simple sketches to complex designs this app works! Still learning and enjoying it.
