App Prototyping with No Design Skills - Quick Guide + Tools


App prototyping is an important step on the way prevent a mobile app from failure. It supports cost efficiency and adjusting vision to real users’ needs.

In this article, we are going to take a look at how and with which tools you can prototype an app as a non-developer/designer.

So, let’s begin.

What is app prototyping?

App prototyping is a form of user research. Interactive prototypes simulate how a product will work and allow us to mimic actually using the app.

A mobile app prototype helps to understand how real users interact with a product and, therefore, validate UX design assumptions and assess the feasibility of a product. Prototyping allows seeing the product in action with the lowest cost possible.

What are the 3 types of prototyping?

There are 3 high-level approaches to prototyping:

  1. Paper prototypes – they help the development team and stakeholders to work out a common understanding and a general idea about the future mobile app early in the design process. Mobile app development often starts with paper prototyping which is followed by building clickable prototypes. Plus, paper prototypes can later serve as documentation. What’s crucial, paper prototypes are not the same as sketches, since there needs to be a flow between all the screens which is explained by an assigned person.
  2. Low-fidelity prototypes – these prototypes are often presented in a form of clickable wireframes linked to each other. They can be created in simple tools like PowerPoint or Keynote, or in advanced digital prototyping apps. Low-fidelity prototypes can be expressed also by paper prototypes described above.
  3. High-fidelity prototypes – these prototypes require more initial effort and represent the highest quality, but with the use of prototyping tools like Figma or JustInMind, they can be created by a non-designer. A high-fidelity prototype presents the entirety of the design in one deliverable. It helps to create a product adjusted to users’ needs and achieve it in a more efficient timeframe.
Situations when low-fidelity app prototyping will become handy.

Benefits of prototyping an app

There are various business- and design-related benefits of prototyping an app before the design and development process starts:

  • Building an app prototype allows for validating an early concept by testing it with real users.
  • A clickable prototype presented to real users during user testing allows for validating usability and user experience assumptions.
  • During user testing, you gather feedback and insights from customers.
  • Prototyping creates the opportunity to seek new solutions and explore new ideas early before the development process starts.
  • User testing allows identifying possible improvements and adjust the idea to real users’ needs.
  • App prototyping is often the first step to establishing or validating business goals.
  • Prototyping allows businesses to save money since it’s cheaper to solve problems earlier in the development process.
  • Costs are also decreased thanks to showing a remote software development team a “ready-to-code” prototype.
  • You can also save money on a designer by sharing with them “ready-to-design” wireframes and mockups.
  • Prototyping allows you to share your concept with friends, co-founders, or even investors and gather their feedback.
  • You make sure about what exactly you would like to build.
  • Prototyping is a great first step to development. It helps to prepare documentation and set common development and business goals.
Benefits of app prototyping.

How do you prototype an app as a non-designer?

To prototype your first app you don’t have to be a designer – Use ready-to-use (and often free) User Interfaces and look for inspirations for your mobile app prototyping.

To prototype your first app you don’t have to be a developer – To animate UI and connect views you created, but you need the right tools to do it.

Paper prototyping tools

No brainer, don’t have to use any extraordinary pro software. You can start right away without any special skills. It’s cheap, fun, and enables you to turn your idea into a tangible product prototype.

There are a few tools that can help you:

  • Free sketch templates for web, mobile, and tablet platforms – sketchappsources.com
  • Offline prototyping with stencilsuistencils.com
  • Remember to make your sketches interactive. Just make photos of your sketches and connect them with each other by setting actions between them to get an “app like feeling”. To achieve that, use app like Marvel.

Top tools to use for app prototyping

Adobe XD

Adobe XD seems to be a photoshop killer for UI design – a vector-based, all-in-one tool to prototype a web or mobile app. It’s easy and fast to use. You can replicate existing elements by dragging the borders or change images by drag-and-drop without any manual adjustment. Since Adobe XD is vector-based, you can easily scale and resize elements. It includes tools for creating interactions, transitions, and other dynamic functionalities.


Balsamiq is a rapid, low-fidelity wireframing tool. It’s more about functionality and getting feedback from users, not beautiful UI. It reproduces the experience of sketching on a whiteboard but using a computer. The tool is not designed to create high-fidelity prototypes.


Figma is an all-in-one tool similar to Sketch. It offers various tools, flexible styles, and a variety of plugins, like Figmotion for creating advanced animations or Autoflow for illustrating user flows. Figma styles allow you to create a consistent design. With Figma, you can easily build a high-fidelity prototype.

Fluid UI

FluidUI is a smart prototyping tool with a strong focus on simplicity and communication. It’s equipped with built-in high and low fidelity UI components libraries, live team collaboration, device previews, and video presentations. That’s what makes it a top-notch solution for designers, product managers, and founders.
