GUI Design Studio in action

User Interface Designs and Instant Prototypes Without Coding

GUI Design Studio version 5

What is it?

Wordsmith Example

GUI Design Studio is a code-free, drag and drop user interface design and prototyping tool for creators of Web, Desktop, Mobile and Embedded software applications.

  • Design screens or web pages
  • Add user interaction behaviour
  • Test as a running prototype

Who's it for?

Web Real Estate Example

Software Designers, User Experience Professionals, Business Analysts, Developers, Project Managers and Consultants. Anyone designing or specifying user interfaces.

  • Document product ideas
  • Create project proposals
  • Create design mock-ups

Why use it?

Internet Phone Example

Quickly lay down ideas and test them out in a low-cost, risk-free environment and avoid expensive implementation rework by getting the right design agreed upon first.

  • Verify designs and requirements
  • Explore alternatives
  • Evaluate different usage scenarios

Step 1: Turn Ideas Into Visuals


So you've got a rough understanding of your application's requirements. Ideas are forming in your head. Now it's time to get them down in the form of screen or web page visuals.

Start a new project and create some designs.

With each design file, GUI Design Studio gives you a big canvas to work with. Really big.

And because of the unique way it uses what's on the canvas, you can decide what's important and what's just a passing thought to hang onto for later.

Push different ideas into the margins and mix them around. Or use them as a new train of thought in a quickly duplicated version of a design.

App Screens

120+ Built-in Design Elements

Create screens using standard Windows controls, Web elements and other generic elements. Provided variations speed up construction. Combine elements to create custom controls and further variants.


Custom Widgets and Libraries

Create your own set of commonly used elements, and groups of elements. Turn any design file into a custom element for reuse. Package custom element libraries for sharing with others.

iOS Design Library

Reuse Components and Masters

Break your projects down into smaller component designs that can be reused on any number of other designs. Changes to the original component are instantly reflected wherever they’re used.

Component Example

“As a User Experience Designer, I need to convince stakeholders that my designs will meet their requirements. With GUI Design Studio I was able to produce a pseudo functional prototype in a very short amount of time that showcased my designs and enabled stakeholders to see how those designs would fulfill their requirements. Caretta Software's very quick response to questions and feature requests was a major contribution to the success of my delivered solutions.”

Step 2: Add User Interactions


The closer you are to a working application, the more insight you'll get into how well it meets requirements.

Static mockups are a great start but they don't tell the whole story. User flow is important in an application, so you also want to describe what happens on each screen and explore their relationships.

  • How do you get from A to B?
  • What happens when you press this button or that button?
    Sometimes it's obvious. Sometimes it's not.
  • What are the different states a screen can be in? What do they look like?

You want to communicate these ideas in a manner that's quick to grasp and easy to understand.

Ribbon Bar Actions

Graphically Depict Screen Flow

Go beyond simple screen links and slideshows with multiple types of navigation, modal layers and on-screen effects. Make connections from practically any element.

User Flow

Multiple Use Case Scenarios

Add use case scenarios to any action and change the flow of the application accordingly. Enter business rules for each scenario condition, based on user-entered data and option selections.


Dynamic and Tabbed Interfaces

Easily create tabbed interfaces and dynamic content panels that may be nested inside one-another for complex applications. You can even control them from simple data value assignments.

Tabbed Interface

“In the last four weeks I've prepared a new rich GUI design for our Money S3 software – a classical ERP system for which we have 100,000+ customers. Caretta Software really helped me, as it was much easier to draw the prototype in GUI Design Studio and stay focused on layout, than directly make the prototype using .NET and DevExpress components. Thanks!”

Step 3: Test your prototype


With one click you can instantly test the design you're currently working on or run the whole project prototype from your designated starting point.

No coding and no waiting for compilation.

This makes the turnaround between design and testing extremely fast for maximum productivity. Make a small tweak to your design and test it instantly.

Only when you test with a working mockup do you uncover all the hidden questions that are lurking behind your design...

  • Does the structure and flow make sense?
  • What happens in this case or that case?
  • What's missing?
  • What can I leave out?
  • and many more, besides...
Prototype being tested

Instant Prototype Execution

Press 'Run' and your prototype opens in its own full screen window (to avoid distractions), with a pseudo-browser mode for web-based designs.

Running Prototype

Fast Scenario Testing

Save time testing different scenarios by creating sets of data you can apply at any time to quickly fill forms in a repeatable way, and without error.

Apply Data Set

Export Snapshots

Capture the moment by grabbing a snapshot of your running prototype as an exported image. Use this to highlight areas of the design for further discussion.

Exported Snapshot Image

“Using GUI Design Studio, I spend less than one hour prior to the meeting to get the forms ready. Then during the meeting, if we decide to change the design, I make all the changes on the spot. Using the Simulator, we can see exactly how each change might affect application flow. We now generally reach an agreement during a single session. Then I just circulate one copy of the spec for signatures. I save 4 to 7 hours a week per project.”
