From pitching app ideas to investors to sharing the project progress and goals with the team, prototyping is one of the key steps in mobile app development. It helps app developers and owners go from concept to product seamlessly.

Prototypes can help overcome any bottlenecks, avoid any pitfalls, and reduce the chances of resource wastage that otherwise occurs due to improper planning, iterations, last minute changes, and more.

So, continue reading and find out all that you need to know about mobile app prototyping as a beginner. Find out how prototypes are different from wireframes and mockups and what roles do they play in an app development projects.

What is mobile app prototyping? 

Mobile app prototyping is the process of creating interactive app demos. App prototypes are created to give a visual and functional experience of an app before launching it as a full-fledged product. Prototyping can be used by developers and app owners for research, budget planning and allocation, supporting investor pitches, backing research, internal team communication and sharing, and more.

Prototypes can also be tested and shared to get feedback in the preliminary stages of an app development project. Prototyping is different than just creating a blueprint of the app as it ensures a more advanced simulator-like interactive experience and lets developers or stakeholders review the features, design, buttons, etc.

While the actual programming and content corpus may be missing, a prototype still gives a neat idea of an app’s goals and workflows. It may contain user interfaces, important app screens, function simulations, and more. Prototyping can also help with testing multiple ideas before finalizing one, getting rid of unnecessary clutter and making valuable changes to a project.

What is the difference between a prototype, mockup, and wireframe?

The terms prototype, mockup and wireframe are often used interchangeably. However, when you put them under a microscopic scan, those three differ from each other. So, how is prototyping different from wireframing and creating mockups? Let us find out!

However, before we tell you what each of the three means, you must learn about the term fidelity. Technically speaking, the term fidelity was originally used to define the quality of music or audio recordings. However, software designers and developers borrowed the term to define the potential of their products.

With respect to creating demos in app development, fidelity defines how elaborate and interactive the model is. For instance, a high-fidelity demo will have more details and interactive features than a low-fidelity demo.

Now prototypes, wireframes and mockups essentially differ from each other based on their fidelity. Prototypes have high fidelity as they may include more functional elements, branding motifs, meaningful content, and interactive features. Similarly, mockups may have high to medium fidelity and wireframes will have low fidelity.

Unlike hi-fi app demos, low-fi mockups and wireframes contain less content, have less design accuracy and elements and lack interactive features. Thus, low fidelity mockups and wireframes are only suitable for brief detailing on products that need to be put out in a short time for an early consensus.

Here is a table that underlines the differences more clearly:

Note that the table above is just a summary and representation of what the three types of app demos can be used for and how they can be differentiated based on their purpose, time line and resource requirements. However, depending on the uniqueness of the project, these attributes may also differ and thus the choice should be based on all such considerable factors.

Why is app prototyping important?  

“There has never in the history of new technology been an example where the first version out of the gate has been the right version.”Tim Brown, Co-chair & former CEO of IDEO

While several potent apps failed in the past, most of them managed to nip the shortcomings in the development stage and go on to become a success. This is why prototyping is important. In fact, over the years, it has become a significant precursor to mobile app development.

From getting feedback on UI/UX to getting all the stakeholders on the same page, prototype has several advantages. Here’s why prototyping is important in app development and what benefits it entails:

Visualize and validate concepts

In primary stages, any project is nothing but a bunch of ideas. However, in order to give it the perfect shape and iron out the creases, the ideas must be validated. After all, not every idea and suggestion will be viable and only some will make it to the end. This is where prototyping comes into play. It helps teams create face values and visualizations for their ideas and get them validated.

Collaborate with stakeholders

Whether it is a UI designer that will give shape to your idea or an end user who will bring in revenue, it is important to align your stakeholders with your product. Creating prototypes enables you to share the product with your team and get their inputs and feedback. It is easier to collect feedback and recalibrate the ideas and product at this stage. It also ensures that all the involved parties are on the same page regarding the product and can work coherently to ensure timely launch and success.

Test ideas, design, and content

As mentioned above, it is important to test different ideas and retain the ones that have the maximum potential or are viable. Similarly, it is important to test various aspects of an app including the concept, design, content, features, functionalities, workflow, navigation, etc. Creating prototypes can help you run it through different experts and get feedback on the same. It can also help you test the various app elements and overcome any flaws or chasm in the project.

Gain the trust of investors

Most apps require investment and funding. Evidently, it becomes easier to earn the trust and confidence of investors when you can actually show them how your app will look, feel and work and what the mission, vision and scope of your projects are. App developers can simply create prototypes and show them to the investors or direct customers who want the process to be transparent. It will give them a neat idea of the app and eliminate room for any concerns or miscommunications.

Optimize budget and resources  

Launching an app and then finding out flaws that need rectification is a hazardous practice. On the other hand, having a fool proof demo of the app and then taking it into development and turning it into a commodity is a smart move. It helps app owners avoid wastage, fast-track app development timeline and save monetary and other resources. Therefore, creating app prototypes will help you avoid any last minute expenditure and also save you time.

How to create a mobile app prototype?

Now that you know what a mobile app prototype is and why it is important, let us tell you how you can create one. Here is a step-by-step guide to creating an app prototype:

Step #1: Research and find your app idea

The first step should be to identify the problem that your app will solve and outline its mission, vision and goals. Once you have found your app idea, start conducting market research and list all the factors that are ought to influence your development journey and define your app’s success.

Step #2: Underline core functionalities

Once the ideation part is done, you can proceed to work on the look, feel and functionalities of the app. List the features and functions based on your industry, niche and app type and prepare a plan and budget accordingly. This will also help you in mobilizing your staff and allocating the right work to the right teams.

Step #3: Start with low-fi demos

Instead of straightaway jumping to prototypes, you can start with basic sketches. Create wireframes to define the app architecture and then proceed to mockups to project a visual idea of the product. These low-fi demos and mockups can be later scaled to create full-fledged prototypes. Get consensus on the demos and make changes if needed.

Step #4: Add UI/UX elements to the demo

Once basic caricature is drawn and tested to assess the workflow and app architecture, you can get UI/UX designers onboard and start adding visual elements to create your demo app. This will turn your wireframe into a prototype that can be shared with stakeholders in order to give them a visually interactive idea of the product.

Step #5: Test and evolve the prototype

The most significant purpose of prototypes is to get rid of any issues in their infancy. So, collect feedback using the prototype and make changes accordingly. Once you achieve a design that is perfect and flawless, you can go ahead and turn the prototype into a product. Create and deploy your app and watch your idea come to life.
