Prototypes, what are they?

Prototypes are a great way to test an idea or concept before building it into a full-fledged product. They allow you to work on something without worrying about the consequences of making it public or using real user data.

This article will teach you everything you need to know about creating and using app prototypes so that you can start testing your ideas immediately!

What is an App Prototype?

An app prototype is a rough version of an application that was produced to test the usability and ease of use. Prototypes can help you visualise what your final app will look like and can save you time if you find out it's not valuable enough by using it.

An app prototype allows you to test the functionality and see how the app looks. It's a great way to get started before developing an app and can save you time and money.

What are the benefits of an Interactive App Prototype?

Interactive app prototypes are a great way to test an idea's feasibility and see if people would use it. They can help you identify your target audience's needs, find potential design problems, and optimise your user experience.

Here are some of the benefits of using an interactive app prototype:

  1. You can test the feasibility of an idea.
  2. You can quickly and easily identify the needs of your target audience.
  3. You can find potential problems with your design before you spend more money on development.
  4. Your user experience will be optimised based on feedback from users.
  5. You can learn much about user behaviour and how people interact with your app while testing it in the prototype stage.
  6. You can quickly and easily make changes to your prototype based on user feedback.
  7. You can learn a lot about how people interact with your app and how to improve it.

How do you create an Interactive App Prototype?

When you are thinking about how to create an interactive app prototype, the first step is to think about what you would like your app to do.

Once you know what you want your app to do, the next step is to develop a prototype that shows how your app would work. There are a few different ways to create a prototype, and each has advantages and disadvantages. (More to read about UX Design Best Practices here.)

Once you have all of the necessary ingredients, follow these simple steps to create your interactive prototype:

  1. Choose a concept or idea to explore.
  2. Brainstorm potential features that could be included in your product.
  3. Develop prototype designs that illustrate how each feature could work.
  4. Test the prototypes with potential users to see what they think.
  5. Make any necessary adjustments to the design based on user feedback.
  6. Present the final product to potential investors or customers.
  7. Celebrate - your prototype is now a reality!

The Different Types of Interactive App Prototypes

There are many different types of interactive app prototypes, but all have one common goal- to help improve the design and function of a product or service. Here are three examples of prototypes and their purposes:

Low-Fidelity Prototypes

A low-fidelity prototype is a simple model or simulation of a product or service used to test the basic design and functionality. It lets you quickly learn how people will use the product or service and whether it meets their needs.

By using low-fidelity prototypes, you can see what the final product might look like without building it.

Medium-Fidelity Prototypes

A medium-fidelity prototype is a more advanced version of a low-fidelity prototype with features still in development. It allows you to test specific product or service aspects and is often seen in mockups.

It is a process of creating a prototype model of a product, service, or system to test assumptions, validate assumptions and find potential problems. Prototypes provide an early view of the product that can be used for feedback and testing.

High-Fidelity Prototypes

A high-fidelity prototype is the most completed version of a product or service and includes all the features that will be released to the public. It allows you to test detailed designs and see how people interact with the product.

The purpose of a prototype of this type is to test and validate the feasibility and usability of an application. In addition, they are often used to help developers better understand how their applications will work. Prototypes can be created in various ways, but all share some common characteristics: they are fast to make, cheap to maintain, and easy to change.

Testing on different devices is an absolute must

How to Test Your Interactive App Prototype?

Testing an interactive app prototype is essential to ensure the design and functionality are correct. There are various ways to test your app, depending on the type and complexity of your prototype.

User Testing

User testing uses real people to evaluate whether a product is usable, helpful, and interesting. You can ensure your product meets their needs and expectations by testing with users early in the development process. (You might be interested to read more about How to you engage your audience here.)

User testing can identify features that are too difficult or confusing to use or irrelevant to the target audience. It can also help you determine which features are most popular and whether there are any user feedback or design problems. Then, using user testing during the design phase, you can create an app that is easier for people to use and more effective in achieving your goals.

How to create an automated prototype with Reptile

First, ask your users about the design, how easy it is to use, and whether they have suggestions for improvement. Then ask them to provide feedback on specific features or areas of the prototype.

Another way to test an app prototype is through functional testing. It involves testing the app’s functionality by simulating user interactions and verifying that all features work as intended. This type of testing can help you identify any problems early in the development process, saving you time and money.

A/B Testing

App prototypes can be a powerful tool for A/B testing, helping you to determine which changes in your app’s design are most effective. By creating different versions of your app and using A/B testing to compare the results, you can quickly find solutions to problems and make your app more user-friendly.

Regardless of your approach, using app prototypes is a great way to test the impact of changes on your users’ experience. By comparing the results of different tests, you can quickly find solutions that improve your user experience and increase conversion rates.

Finally, you can also conduct performance tests to see how well the app performs under various conditions. This information can help you make informed decisions about Which features to include in the final product and which may need to be sacrificed for greater performance.

App testing

Test your design in a real app: Reptile

Reptile is a real app platform that allows you to test your designs in an actual app before you go through the time and expense of developing them.

The reptile app prototype platform is an online platform that helps businesses and developers to create realistic mockups of their apps in minutes. It provides a hassle-free way to test user flows, designs, and interface components before launching a complete app development project. (Here is more information on How to prototype your product quicker.)

To test your designs in a real app platform, Reptile offers an easy-to-use drag-and-drop interface. This lets you quickly create a new app. Then, once you have created your app, you can start testing your designs immediately.

Reptile provides developers with a wide range of features and templates to help them get started quickly. You can also find helpful tutorials and reviews of the most popular apps to help you get up to speed on the latest trends. By using Reptile, you can quickly validate the design of your app and ensure that it is ready for launch.


If you're ever feeling stuck in your design process or want to try something new, consider creating an app prototype. A prototype is a simple version of your final product that allows you to test out the feasibility of your idea and see how people might interact with it.

Once you have a working prototype, it's time to start thinking about user feedback and refining your design accordingly.
