What is a Mobile App Prototype?

You may know intrinsically that the right mobile app will make your workers more productive, facilitate better communication between your field and office teams, and cut out a lot of paperwork.

You may already be envisioning an app that will solve your biggest management, sales or operational pain point, but don’t how to approach it or if it’s even possible. This is where a mobile app prototype really shines.

Mobile app prototypes demonstrate an app’s functionality, help you get stakeholder or customer by-in, and provide a way to let users try out the concept, before you invest in a full build out.

What is a Mobile App Prototype?

A mobile app prototype is an preliminary visual mock-up that looks like a real app, and that demonstrates an app’s fundamental design and function, but does not contain working code. An app prototype can be as basic as sketches on paper or as high-fidelity as a clickable, digital model that works on your phone.

Prototypes convey the look and feel of your app, but they are usually not working software. They set the stage for the first functioning version of your app, often referred to as the minimum viable product.

Types of Mobile App Prototypes

Design is always the first phase of creating an app or an app prototype. At Big Fish, we often create early designs on pencil and paper. We then move to digital versions, starting with low-fidelity, black-and-white wireframes, then moving to high-fidelity, full-color designs.

Every mobile app we develop goes through these phases during our app design process. But, we can use these designs to create a prototype at any phase of the process. Each phase offers a prototype with benefits on its own.

Hand-sketched prototype: The most basic prototype is a simple series of hand sketches on paper. Each sketch represents a different screen and you can cycle through the sketches to show the app’s flow. These prototypes allow designers to iterate ideas very quickly, which makes them ideal during brainstorming or strategic planning.

Black and white digital prototype: The first digital phase of app design involves creating black and white “wireframes” representing each screen of the app. These wireframe designs can then be set up with a prototyping tool, such as Invision, to create a clickable visual representation of your app.

At this stage, the design is kept black and white so users focus on functionality in their feedback, rather than the colors and images. These low-fidelity prototypes take less time and investment than a high-fidelity digital version, and they are ideal for confirming the app’s big picture concept and basic structure.

High-fidelity digital prototype: Your high-fidelity digital prototype looks like a real mobile app. Even though the screens are just images—so you can’t type in fields, use the GPS or camera, etc.—the images reflect the intended design, are clickable, and are viewable on your mobile device just like a real app.

Stakeholders will get the truest sense of the user experience before software development begins. This prototype is ideal for businesses that need buy-in from boards, executives, or end-users.

Benefits of Prototyping Your App

Fail Early: A business might prototype their mobile app and discover that what they envisioned is not practical or what their users or stakeholders want. Far from being a waste of time and money, in this case beginning with a prototype saved a great deal in development costs and provides peace of mind and proof to executive teams that a digital solution won’t work.

Get Clarity: More often, prototypes give clarity regarding precisely what you need, and how a mobile app can fulfill on it. They allow you to play with ideas and solicit feedback before investing in developing the software.

Sell Early: Prototypes also perform a significant role in obtaining funding by demonstrating the product to investors, executive boards, or even prospective customers.

Iterate Quickly: Prototypes even benefit businesses that already have a clear mobile app concept in mind by allowing you to cycle through multiple drafts before developing software. You create a better product, with less time and money, by putting effort into the planning stages of developing a mobile app with a prototype, and that’s smart business.

If you have a business app idea that you’d like to prototype, we’d love to help. Please request a consultation with our team to get started. Or, if you’ve spoken with us already and you’d like to add a prototype to your project, let us know.
