, a British electric vehicle manufacturer, is on a mission to create more than just cars.

They understand that to combat the climate crisis, we need transformative solutions to lower carbon emissions, reduce air pollution, and keep waste out of landfills—and we need them fast.

Their solution? To make radical changes to the way we design and produce electric vehicles by

Removing cost barriers to electrification.

Using low-footprint materials made to last.

Designing vehicles to be accessible for a diverse range of users.

To bring such revolutionary ideas to life, you need high-quality tools - and to not be slowed down by confusing code and tech jargon.

That is precisely why Arrival’s designers started using 

 to create automotive UX prototypes—without help from developers and engineers. Here, you can hear from the HMI design team at Arrival on how they create high-fidelity prototypes for buses and vans using ProtoPie. 

Driving is a complex activity that requires a lot of cognitive load.

Any distraction could lead to human error, so to avoid devastating consequences, the car UX design process requires particular care and attention—to every single detail of the experience.

It is essential for the team at Arrival to test every iteration of the vehicle while driving to ensure that everything runs safely.

Let’s look at some of the challenges they faced when designing the user experience for two of their products, Arrival 1 and Arrival Bus.

Arrival 1: Driver-focused UX design for a single user.

 has a modular design that scales to multiple variants, meaning that it is made up of components that you can easily replace to ensure a longer life cycle.

In this vehicle, the focus of the design is on the driver, with considerations for aspects like:

The cabinet area is where the drivers spend most of their time. It has a digital screen designed by the HMI design team, which is also responsible for all physical and digital touchpoints that aim to create better experiences for the user.

Arrival Bus: Accessible UX design for multiple users.

For the Arrival Bus, the prototyping process can be a little more complicated. That is because the team has built the vehicle not just for the driver—but also with consideration for passengers and fleet operators.

These are examples of components that enhance accessibility and showcase integrations between digital systems and physical design:

The floor is flat, making it more accessible and easy to clean.

The poles have touch points that serve as the primary means of communication between the passengers and the driver.

Internal screens around the bus mirror the interaction to let passengers know that a stop has been requested and how much time remains until the bus stops.

At Arrival, the digital team works alongside the industrial design team to form digital experiences into physical products. 

These types of seamless hardware-software integrations allow the HMI design team to create unique experiences, rather than digital experiences based on pre-existing hardware.

The result, they say, is an “experience that almost feels magical.”

How Arrival uses ProtoPie to revolutionize their HMI design process

Led by a guiding principle of product safety, Arrival innovates everything from the manufacturing process all the way to human sensory design in their products.

The design team at Arrival relies on two tools in their workflow.

As a first step, they explore iterations of the product in Figma. In the second step, they build every design component with ProtoPie.

There are two main ways they use ProtoPie, which we will look at in more detail in the below sections.

As mentioned earlier, testing while driving is an important part of the automotive UX design process at Arrival.

The team tests every part of the design rigorously to ensure safety, with a human-centered focus on the person driving the vehicle. 

In the UX testing process, they look at aspects like:

The ergonomics of how people drive while interacting with the screen.

2. Creating a bridge between the physical and digital.

Beyond the screen itself, the team looks at what the physical controllers do and how they appear on the screen. For example, during the automotive HMI design process, they ask questions like:

If you hit the stop button or steer the wheel, how does it look like on the screen while you do these interactions?

How does the vehicle interact to the outside environment?

The next section will look at examples of how Arrival prototypes vehicles with ProtoPie, and how these principles translate to real-life practice.

Examples of vehicle prototypes made with ProtoPie

For the first use case, the design team at Arrival uses a simulator with a real engine, pedals, steering wheel and a screen on the right-hand side. It is designed exactly like the real end product, to allow for quick feedback and new iterations as necessary—even as early as the next day. 

In the second use case, the team created “God Mode” where the user can set the day or change the weather to see how the interface reacts to changing external conditions.

One of the benefits of ProtoPie is that they can have everything in one place, to show to different engineers and stakeholders.

It is possible to display every component in detail, but also as a whole to enhance understanding of every stakeholder’s role in the bigger experience.

The last example is the Arrival Bus, which has internal screens that are all contextual to the bus journey.

The team created a prototype that allowed them to visualize every stage of this journey, which was especially helpful as traditional flat design tools make it difficult to communicate such complex information.

With ProtoPie, they can share a prototype where people can play around with the iteration, tapping interactions like “stop” and “request” and see what happens in response.

Every single one of these examples was built by designers, not developers.

In short, ProtoPie has been the ideal solution to help Arrival increase the speed and quality of their prototypes—empowering them to achieve their goals faster.

Using ProtoPie to Design Tomorrow’s Electric Vehicles

Rapid high-fidelity prototyping has become a critical part of the product design stage.

Immovable images just don’t cut it anymore. After all, there are stakeholders to impress. Deadlines to meet. And markets move faster than ever before.

UX designers are under increasing pressure to provide prototypes that look and feel like the real thing, complete with complex animations and rich interactions.

Anna Rzepka, a senior UX/UI designer from Cracow, Poland, was under such pressure. But the prototyping software she was using couldn’t quickly deliver the complex and beautiful prototypes she needed.

She needed to find a rapid high-fidelity prototyping tool that could bridge the gap between the design, engineering and business departments.

: the problems she encountered with previous prototyping tools, why she turned to ProtoPie, and how ProtoPie helped streamline and turbo-charge her workflow. 

I’m a UX/UI designer by trade, but now my work involves developing beautiful design solutions that run in tandem with business strategy – bridging the gap between the design, engineering and business departments.

 began as my primary prototyping tool – from drafting diagrams and drawing vector illustrations to putting all the visual elements together.

But times have changed – still images aren’t enough to fully convey app behavior. In short, Figma alone wasn’t enough.

It had become increasingly challenging to make complex interactions. Although Figma has the Smart Animate feature, there’s no timeline to precisely adjust keyframes. Neither is there conditional logic, advanced formulas, nor variables. I kept on having to compromise, and high-fidelity prototypes were hard to build. 

I tried everything. Some tools were great for designers but useless for engineers and troublesome for stakeholders.

 was a cinch. I could make screen transitions in a blink of an eye. Annoyingly, it’s only available for Mac users and our programmers use Windows.

, curious about its Behaviour Designer. The idea of creating micro-interactions without transitioning to a new screen was tempting. Yet once again, sharing merely video recordings with my teammates became tedious.

 gave me a lot of control over my UI animations, and the Patch Editor reminded me of Blender Nodes. It was a let-down to find out you need to install the software to preview the files.

. It allowed me to write my code and fully unleash my creativity. But more often than not, it was overkill.

I downloaded ProtoPie to test the waters ten months ago and quickly discovered that it was just what I needed – a powerful prototyping tool that connected the worlds of design, business, and technology.

ProtoPie was the missing piece of my workflow puzzle. 

ProtoPie hit the sweet spot. It works with Figma, offers lightning-fast prototyping, and developers can inspect every property from the Interaction Recordings without installing anything.

Learning ProtoPie was easy and endlessly rewarding. I could quickly build my first high-fidelity prototypes with little effort and seamlessly share them with my colleagues ­­– regardless of operating system or software.

Getting started was simple. There were plenty of resources to jump-start prototyping – ­ detailed 

. Moreover, example files to learn some handy tricks from other designers.

ProtoPie tickled the curious part of my brain. I love experimenting and exploring unknown grounds and ProtoPie allowed me to push through previously insurmountable creative horizons.

In the end, it was genuinely fun. Never before had I enjoyed playing with a piece of software this much. To put it mildly, I was in love – I wasn’t just using ProtoPie at work, I was playing around with it after hours.

What struck me most of all was the mind-blowing extent of control it gave me. I could create immersive experiences in the blink of an eye. I didn’t need GIF workarounds because I could use my production-ready Lottie animations. Not to mention, everybody could effortlessly view my prototypes in a browser or on mobile devices.

ProtoPie allows me to be creative and incorporate animations into my visuals. To my mind, ProtoPie adds a pinch of spice to my creations.

ProtoPie helps me quickly build complex micro-interactions and test different concepts – invaluable when I want to show clients how new features will look when implemented.

ProtoPie is an incredible time-saver, enabling me to streamline my process and significantly boost productivity. Rapid prototyping allowed me to test concepts without involving developers. It was a substantial cut-back in spending and helpful when it came to developer handoff.

And most importantly, ProtoPie improved communication within our teams. The Interaction Recordings leave no space for any guesswork. 

I currently work on an e-commerce drugstore assignment where I extensively use micro-interactions. ProtoPie allows me to guide the users through the flow. Also, it helps manage eye focus and highlight the essential layout elements.

Additionally, it helps establish a consistent brand voice and image. It’s visible clearly when something on the website goes wrong. Empty states, error pages, and invalid inputs are perfect spots to try something more playful and fun.

ProtoPie enables me to tell a story and drive conversions in places usually considered a dead-end.

A Designer’s Journey to Discovering ProtoPie

Prototyping is a critical part of the product design stage, allowing UX designers to put their ideas into a living reality.

However, many prototyping tools leave little wiggle room for experimentation. Either they’re too simple, or they’re too complex.

Designers have deadlines to meet. Stakeholders to impress. They need a rapid high-fidelity prototyping tool that can create realistic and rich interactions—code-free.

We spoke to Yasir, the Head of Design at 

, a multi-chain wallet-to-wallet messaging app.

In this sweeping case study, we cover everything from 

 and color to tilt effect and sharing your prototypes on the cloud. How 

enabled Yasir to experiment with his ideas and eventually, how those designs went viral.

It’s easy to become detached from the products we use. After all, a product doesn’t have life. Why should a product interact with us?

But touch is important. When we interact with the real, living world, that world reacts to us. A blade of grass may shimmer in the wind and light. A cat might purr on our approach. A shadow might fall as we move in the sunshine.

I want to enable users to engage emotionally with their products. To do this, I design emotional interactions and patterns for touch interfaces.

As a mobile-focused designer with a love of touch interactions, I have fairly complex prototyping needs in terms of product design.

Naturally, I’ve tried many different tools to meet those needs, but the products have either been too primitive or too complex. Every designer worth their salt knows that when you’re in the design stage, racing against deadlines, you don’t have time to learn a coding language.

In short, I require a prototyping tool that can work in harmony with design programs and churn out crazy ideas quickly—in short, a code-free high-fidelity rapid prototyping tool.

I started prototyping with Principle, a decent rapid lo-fi prototyping tool but primitive in its simplistic interactions. Then I used Figma to test the flow of particular products, but I found its animations to be lackluster and the design of complex interactions always fell short of the hurdle.

One of my colleagues introduced me to ProtoPie when I was working on a project at my previous company 

We needed to access the device's sensors and test our designs with more realistic prototypes. ProtoPie allowed us to test our designs realistically and enabled us to generate different ideas. I’ve not looked back since. It’s the best high-fidelity prototyping tool out there.

I had only been at the job for 2 months, and I wanted to motivate my team.

I kicked things off by designing the onboarding screens. After all, the way you welcome the user is a critical moment in the user journey. I created the designs in Figma and used ProtoPie to experiment with different animation ideas.

Initially, I was trying to create a simple parallax effect by just moving the logo and the background. I began to wonder. What would happen if I connected different sensors to different units?

The colors of the app hadn’t been decided yet. I suddenly thought, 

What if the colors of the app changed according to the angle at which you hold the device?

What if the user gets to decide what colors they see on the screen?

Buzzing with excitement, I began quickly prototyping the idea and shared it on Twitter. That was an eye-opener—the idea got far more attention than I expected. Indeed, some designers told me how inspiring it was. Since then, it’s become a core element of G.host’s design language.

Why ProtoPie is the best hi-fi prototyping tool

We couldn’t have done it without ProtoPie. It allowed us to test the idea quickly and realistically—without engineering costs. It makes usability testing a breeze.

There’s also the collaborative nature of ProtoPie to consider. Sharing prototypes with colleagues used to be a hassle, requiring far more complex processes. With ProtoPie, all you have to do is scan a QR code and voila! You can easily share your prototypes on the 

—you don’t even need to download ProtoPie.

Handing a prototype over to the engineers is usually a difficult process, but ProtoPie’s interaction recipe saves so much time. The engineers can view the UI animations with visual documentation that covers every action and detail of each trigger and response—playing the animation at any speed and easily understanding which values they should use.

ProtoPie is more than good. I’ve been using ProtoPie for 2 years and I love it—it unlocks a lot of potential ideas in the interaction design process. It gives me room for experimentation.

ProtoPie is the best hi-fi rapid prototyping software out there for experimentation.

Experimentation is crucial. If I had to give you any unsolicited design tip, it would be that creative ideas usually emerge from a remix of different concepts—you won't find anything new if you don't try hard enough to mix things up.

How ProtoPie Helped G.host Multi-chain App With Their Innovative Prototyping Needs

We have become detached from musical experiences.

Only decades ago, music lovers would carefully go through each vinyl before finally settling on an album. Now, individual songs are just a click away and we don’t listen to albums as singular works of art.

 address this alienation—an interactive multi-screen device that connects directly to your music streaming app complete with a touch screen and beautifully integrated visuals.

The Tile team needed the best prototyping tool out there to turn their idea into reality—a rapid hi-fi prototyping tool that could strike the perfect balance between seamless tech and gorgeous design. They turned to 

In this mind-blowingly original ProtoPie case study, we caught up with 

—Dutch technologist and postgraduate student at Umeå Institute of Design—to find out more about their project, and how ProtoPie fulfilled their high-fidelity prototyping needs.

Prototyping is an essential part of my product design process. It allows you to be confronted by the potential of your ideas—to explore, validate and iterate concepts.

I love fusing the physical and digital worlds—gluing together hardware and software and seeing what works. To do this, I need a rapid prototyping tool that enables me to demo hi-fi interactions.

For most of my career, I used a combination of 

. Only, there was a problem. Processing is outdated, especially when it comes to animation. I occasionally used 

, but was always disappointed by the lack of controls for smart animations.

I was introduced to ProtoPie while working at 

 and I’ve not looked back since—it has helped me turn my ideas into reality, allowing me to explore the infinite horizons of interaction design.

When it came to the Tiles Project, I needed high-fidelity prototyping software that could seamlessly link with hardware like Arduino.

I didn’t need the freedom of fully coding, but I needed something with a bit more pazazz than Figma. And I needed speed. The best prototyping tools allow for rapid prototyping and give you detailed control of animations and interactions. This gives you more freedom to focus on exploring and designing than simply developing.

That’s why I turned to ProtoPie. Not only is it the best prototyping tool for collaborative projects, but you can link it to hardware like Arduino in a code-free environment with high-precision animation controls and built-in triggers. 

Essentially, ProtoPie gives designers the freedom to make advanced structures with variables, triggers, and responses—all in a code-free environment. In other words, ProtoPie strikes the perfect balance between design and tech. Moreover, it’s a scalable tool ideal for collaborative projects and works on almost all devices.

And ProtoPie saves time. It’s an intuitive, easy-to-use rapid prototyping tool that fulfills 99% of your prototyping needs.

But don’t be deceived by its easy, user-friendly layout. ProtoPie is a breathtakingly powerful rapid prototyping tool. You’ll know what I mean if you’ve ever read through their documentation on triggers, responses, formulas, and variables—it’s an endless horizon of creative potential.

: How ProtoPie helped Kay accomplish his objectives

Listening to music today can be an anti-climactic experience. The next song—any song in the world—is just a click away. Tiles was an attempt to address that. 

In a collaborative student project, we built a multi-screen device that allows users to select albums, scroll through album artwork, control volume, and so much more. 

ProtoPie worked seamlessly with Arduino and we were able to build a usable prototype in 2 days. Arduino allowed me to attach multiple sensors to the user interface I built in ProtoPie, which enabled me to quickly change interfaces while trying it out with the actual hardware.

ProtoPie is so intuitive, fast, and easy to use. It saved me time, allowing me to focus on shaping the behavior of the product itself.

It was only a mockup, but look at the fidelity of the interactions—it’s fast and responsive and allowed us to demo other functionalities with speed and precision. Better still, as a showcasing gesture, ProtoPie couldn’t have been more powerful: it’s not every day you can play interaction sounds as a trigger response on a prototype.

Building An Interactive Music Device with ProtoPie

 is a workplace mental well-being platform based in Aotearoa, New Zealand. Its mission is to improve the well-being of 100 million people and “save 100,000 lives”.

Groov is a unique ProtoPie case study—after the product design stage, the products are sent to a team of in-house clinicians who rigorously test them to ensure that everything is based on sound scientific evidence. Naturally, they require a rapid prototyping tool that can quickly create high definition, realistic prototypes.

We caught up with Maya McNicoll, the Senior UX Designer at Groov, to find out more about how Groov uses ProtoPie to create safe-to-use mental well-being platforms. 

Groov designs tools that help people feel better. We comprise a team of 50 people based across New Zealand, Australia and the US.

, which is used for daily, personalized well-being and inspiration, and 

, for interactive online learning. There’s also a 

, which we use to measure well-being insights, and a 

—for helping workplaces introduce positive well-being habits.

Our team encompasses a wide range of disciplines. There are in-house UX designers and content creators, marketing experts and product managers. Critically, we also have an in-house clinical team who ensures that everything we release is clinically sound and evidence-based.

I work on the Groov app. On any given day, I might be focusing on prototyping, user flows, discovery research, user testing, or working on our own product design system.

While the role is challenging, the hard work is made worthwhile by the fact that I’m improving the lives of people in a meaningful way. I can’t emphasize enough how fulfilling it is—particularly when I hear from those whose lives have immeasurably improved as a result of Groov.

Being a mental well-being platform, the single most important thing for Groov is that our products are safe for people to use. We have zero-tolerance for risk. This adds a whole new layer to usability testing.

We encountered a problem. New features that tested well after the UX design stage were being rejected by our team of in-house clinicians, making the whole process longer and more arduous.

However, it wasn’t ethical for the clinicians to sign off on static user flows. In short, we needed a high-fidelity rapid prototyping tool—one that would allow us to speedily create realistic prototypes that the clinical team could test as though they were using the real thing. 

"We needed ProtoPie—we just didn’t know it yet."

Then the pandemic hit. The New Zealand Ministry of Health approached us, asking if we could release our app for free to everyone in Aotearoa—to help them alleviate the increased mental suffering brought on by government-imposed lockdowns.

They wanted to see some demos—we needed to create a high-fidelity product design quickly and affordably, testing ideas that would normally require a whole development team.

How ProtoPie helped Groov achieve its objectives

The Ministry of Health loved the prototype and agreed to support a free public version of the app.

That’s where ProtoPie has solved most of our problems—user testing. Stakeholders will be thoroughly convinced of your product’s merit upon seeing a user genuinely enjoying your prototype.

It was so successful that the partnership was renewed in March 2022, and now everyone in New Zealand has a free-to-use Groov app at their fingertips. However, we’re still selling our original version to businesses across New Zealand, Australia, and beyond.

The next big hurdle was engagement—how could we create an app that was safe, accessible, effective and fun to use? ProtoPie proved to be the game-changer. As soon as we have an idea, our UX designers can create mock-up prototypes quickly, complete with complex interaction designs. 

So, when fellow UX designers ask me, “Is ProtoPie good value for money?” I always point out that as a rapid prototyping tool, ProtoPie is second to none: time is money, and we’ve cut our iteration time in half.

While it’s also fun and intuitive, once you get the hang of it there is so much wiggle room to grow. The 

 feature is popular among the UX design team, but for me, it’s not just about the tool—it’s the support that comes with it. Whether it’s the

ProtoPie Fits Right in the Sweet Spot Between Usable and Powerful

 is a global digital agency and innovation consultancy that operates at the intersection between technology, data, and creativity. It helps some of the world’s leading companies strengthen their brand and grow their customer base through digital product design, including Google, Nike, Verizon, Samsung, and Toyota.

However, they can only do this through rigorous UX prototyping and by conducting extensive user research. We caught up with Anthony Baker, Vice President, Head of Technology Strategy at R/GA, to learn more about how they use 

 for their rapid prototyping needs and to generally speed up their design workflows.

Every digital agency knows there’s a huge difference between concepts, decks, and static representations of an experience versus what the real thing will actually be like. We might have several meetings with a client and present a solid vision of what we’ll produce, but even then, nobody knows exactly how it will turn out.

Well, not until you begin UX prototyping.

We leverage prototyping for bringing concepts to life, for user testing, and for market-fitting research. It helps to accelerate the implementation of creative and technical solutions. 

At R/GA we’re constantly experimenting, using the latest, most innovative digital product design tools to push the boundaries of creativity. Our team is full of amazing ideas—but even the best ideas need to be validated, polished, and tweaked. We rely on UX prototyping to help us do this.

In today’s business landscape, speed is of the essence. Companies need to react quickly according to how consumers think and behave, which is constantly changing. Digital prototyping is therefore crucial for all companies.

By creating high-fidelity prototypes at an early stage, you can then begin iterating and fine-tuning your concepts. This is a real competitive advantage. The quicker you can bring your ideas and concepts into life, the more opportunities you can generate for your clients.

How ProtoPie helps R/GA solve its digital prototyping challenges

ProtoPie’s rapid prototyping capabilities help us close the communication gap between what a client expects and what we want to deliver. Our team can prototype realistic experiences at speed, gain feedback from the client and customers at an early stage, and iterate on an ongoing basis.

This makes the creative process as efficient as possible. We can identify if our approach will work, and if not, course-correct as soon as possible. ProtoPie has saved us a ton of time and wasted effort over the years—we can make sure we’re always on the same page as our clients throughout the design process.

"ProtoPie offers the best of both worlds—it’s straightforward to use yet offers a wide variety of rapid prototyping features. We’d never consider using another prototyping tool." 

We were immediately impressed by how intuitive ProtoPie is. The tool’s underlying architecture (with objects, 

) just made sense. It felt natural to use, which meant our team easily got to grips with how it worked. There’s no point in implementing a tool that nobody understands how to use.
