If you want to develop a mobile app, you just have to know what is a mobile app prototype and why it is so important in the whole development process. Currently, mobile application marked is just swamped with applications. That is why when you decide that your app is to go live, you must be sure that it meets all needs of the end user.

Recently, a lot of publicity has been gained by UX design, aiming to provide an optimal user experience before the proper development phase. It is within the UX design stage that mobile app prototypes are created. In mobile app development, prototypes check whether the concept behind the app will suit users and whether the entire UX design, user journeys, etc., have been designed the right way without spending a huge budget.

This article will cover all the issues surrounding mobile app prototypes in more detail and provide knowledge of the ten best tools you can use for prototyping focused on a mobile device!

Let’s start with the basics.

What is a mobile app prototype?

In simple words, a prototype is an early sample, model, or release of a product built to test a concept or process. A prototype generally evaluates an idea or product’s feasibility, design fit, market appeal, and potential manufacturability. In the case of mobile app prototypes, they are intended to illustrate how the final application will function. Such prototype is most often created with special tools that allow to quickly and effectively create a very basic interactive version of the product.

The mobile app prototype allows you to present user flows and journeys and check if they have been designed correctly. At this stage, many mistakes and dead ends occur. Because they can be located and removed early, later development will be much less expensive and time-consuming.

The prototyping process can also show opportunities for implementing solutions that the team didn’t think of when creating UX design. After the prototype is ready, user testing can be carried out. This will give even more valuable insights into how people interact with the product. Based on the findings, the prototype can be improved. Mobile app prototyping is a continuous process that lasts as long as all business and user needs will be met.

TL;DR – The mobile app prototype is a very important tool in the design process. It allows you to test user flows and journeys, find mistakes and dead ends, and improve the overall UX design. User testing is also essential to ensure that the product meets the needs of its users.

Types of mobile app prototyping

Two major types of prototypes can be used for mobile app design. The type of prototype should be determined by the stage of the design process, the resources available, and the goals that need to be achieved.

Low-fidelity prototypes

Low-fidelity prototypes are typically created early on in the design process. They are quick and easy to create and don’t require a lot of detail. Low-fi prototypes are often used to test high-level concepts and ideas. As they don’t consume many resources, lo-fi prototypes are a great way to check whether the core features of an app make sense.

High-fidelity prototypes

High-fidelity prototypes are more detailed and closer to the final product. They are usually created later on in the design process when all the major components have been worked out. Hi-fi prototypes are often used to test specific functionality and user flows. Creating a high-fi prototype can be time-consuming and require more resources than a lo-fi one, but getting more accurate feedback from users can be worth it.

Why is it worth prototyping?

There are several reasons why prototyping is a valuable part of the design process, if not the most valuable of them all. Mobile app prototyping can help you:

  • Test new ideas quickly and cheaply
  • Get feedback early on in the process
  • Identify areas that need more work
  • Make sure everyone is on the same page
  • Help developers understand how the app should work
  • Creating a prototype can save you time and money in the long run by helping you avoid making major changes later on.
  • It also allows you to get feedback from users early on, so you can make sure you’re building something people will actually want to use.

Best mobile prototyping tools

You already know what mobile app prototyping is, what its types are, and why you should consider the creation of clickable prototypes in your development process. Now we will present you with 10 tools that will allow you to create your own mobile prototypes.


InVision is a prototyping tool that enables designers to upload sketches, wireframes, and photos to create interactive prototypes. It’s great for quickly testing out design ideas and getting feedback from clients or team members. Plus, it’s a free prototyping tool!

InVision also includes features such as Hotspots, Interactions, Transitions, Headers, Overlays, and perhaps the most important feature – a prototype can be built for multiple devices! Additionally, users can leave comments directly in the prototype, thanks to which getting your feedback is easier than ever!


Proto.io is a tool that allows you to create high-fidelity prototypes that look and feel like the real thing. It’s great for testing out detailed designs and animations. Proto.io takes advantage of a drag & drop interface, thanks to which everyone can build their own prototype! It also has a large base of pre-made UI components (250+), Templates (1000+), and digital assets (6000+).

With proto.io, you can easily go from a lo-fi prototype to a hi-fi one! Proto.io has many features: Animated icons library, Sound Effects library, Easy drag-and-drop upload, Plugins for Sketch, Figma, XD & Photoshop, Touch events & Gestures, and many, many more! It requires a subscription, but you get a 15-day free trial.


AppCooker is a tool that helps you quickly create prototypes for iOS apps. It includes a drag-and-drop interface and pre-built templates, so you can create a prototype in minutes. Plus, it’s only $9.99 to use!

With AppCooker, you get all the native iOS UI elements to play with, so your prototype will look and feel like the end product in no time. With AppCooker, you can also add links and transitions, thanks to which you will be able to create the whole user journey within one software!

Adobe XD

Adobe XD is a vector-based design tool developed by Adobe. It’s used for creating user interfaces, wireframes, and prototypes. It’s simple to use and has a wide range of features, making it a popular choice among designers. XD comes with two distinct modes: Design and Prototype.

Using XD’s tools and capabilities to construct components and add artboards in Design mode. You then switch to Prototype mode to create interactive connections between artboards. Finally, you may share the prototype with your team to preview it. Adobe XD costs US$11,49/mo, but you get a 7-day free trial.


Justinmind is a tool that helps you create prototypes for web and mobile apps. It comes with a drag-and-drop interface and a wide range of features, making it easy to use. Justinmind also offers pre-built templates and libraries of UI elements to help you get started quickly.
