Heady and Melissa Wood Health (MWH) joined forces in 2021 as the digital wellness brand set its sights on the next phase of its digital evolution.
Our concentration on long-term partnerships focused on sustainable growth made us the perfect match for building MWH’s next chapter. Following an accelerated build, MWH’s new owned platform rolled out in November 2022, complete with an expanded website and native mobile apps for Android and iPhone.
We built a custom mobile and web platform for MWH

With the platform launched and in a mature state, our focus turned to scaling — and that’s where the Design System came in.
What Is a Design System?
A Design System is a dynamic framework that serves as the backbone for design and development of a digital product. It creates a unified language and visual coherence within a product or across multiple products, making it faster and easier to scale and evolve a digital ecosystem that looks and feels consistent and harmonious.
A Design System has two main parts
Component Library
Think of it as a catalog of pre-designed elements — buttons, headlines, dialog boxes, headers, footers, patterns, and more — that can be reused across various screens and platforms.
Documentation
Accompanying the components is a set of guidelines detailing how and when to use each element, ensuring consistency across teams and reducing design debt.
Problem Statement
As MWH scaled its offerings and expanded its user base, it was not only crucial that the brand provide a cohesive user experience; to properly set the stage for scaling, we also needed to streamline workflows and facilitate collaboration between teams. With both MWH’s internal team and the Heady team regularly doing design work on MWH’s products, we needed a common design language to unite around — one that would facilitate rapid iteration and meeting tight deadlines.
Challenges
Unify Multiple Products
The first key issue was ensuring unification across both MWH products. MWH subscribers can access its content through both the brand’s website and its native mobile app. Creating a seamless experience across these platforms required a single, unified design approach. This is where a Design System came into play: It became the bridge that connects mobile and web, allowing users to seamlessly switch back and forth between both platforms while ensuring familiarity and ease of use.
Create a Single Source of Truth
The second challenge that a Design System would solve was to tackle the clutter created by numerous disparate design files that had accumulated over time. Every design file created outside a centralized system risks introducing inconsistencies and slowing down the development process. By implementing a Design System we created a "single source of truth," helping to declutter the design landscape. This unified resource allowed new designers to get up to speed quickly and ensured everyone on the team was aligned — not just designers, but also product managers and developers..

Optimize Processes & Workflow
Lastly, we needed to optimize processes and workflows. Without a Design System, any design change could be a time- and labor-intensive process requiring manual adjustments across multiple elements. With the Design System in place, we could make global design changes almost instantaneously, freeing designers to focus on higher-level tasks and empowering developers to implement functional elements more efficiently.

Design Principles
When it comes to designing digital products, consistency is key. That doesn’t mean every screen should be identical, but there should be enough consistency in look, feel, and functionality throughout the product that users feel comfortable and are able to navigate easily.
Systems Thinking
Every Heady design project is approached through the lens of systems thinking. This holistic view ensures that all components are designed to function as part of a greater whole. Systems thinking allows us to focus on the end-to-end user experience, not just isolated design elements, ensuring that all the small components (like buttons and colors) work well together to create a unified experience. For the user, this means easier navigation, consistent visuals, and a more intuitive interaction with the product.
SYSTEM BREAKDOWN
Atomic Design
Creating consistency is one of the biggest values of implementing a Design System — but how, exactly? It all comes down to reusable components. At Heady, we approach Design Systems through the lens of Atomic Design principles.
This metaphoric methodology breaks down the process of building a Design System into five distinct levels, from simplest — atoms, which are the building blocks of all matter — to most complex.
Atoms
The smallest components including branding, colors, typography
Molecules
Atoms come together to form buttons, toggles, check boxes, notifications
Organisms
Multiple molecules create headers, footers, sections
Templates
Multiple organisms on a page come together to create a template
Pages
After injecting the content into the template, you have pages
Using Atomic Design principles means breaking a product’s visual design down into its smallest parts, standardizing them, and then building them back up into increasingly larger, reusable components. Through this process we bridge the gap between designers and developers and ensure functionality and usability is consistent, providing a better user experience.
Design Process
Design System projects are often embarked on as foundational pre-work before any design work begins, but they can also be implemented after digital products are already built as a crucial organizational tool. This was the case with MWH. Given the already mature state of MWH's digital products, our approach was to “reverse-engineer” a Design System by auditing, organizing, and scaling what was already in place.
Before diving into the Design System, we revisited the branding guidelines we had initially created as a precursor to building MWH’s platform. Ensuring that these guidelines seamlessly integrated into the Design System was an essential step for brand consistency.

Categorization via Atomic Design
After documenting the existing design elements, we categorized them into atoms, molecules, and organisms, following the principles of Atomic Design. This allowed us to:
+ Define foundational elements (“atoms” like typography & colors)
+ Develop complex components (“molecules” like buttons)
+ Organize comprehensive sections (“organisms” like headers)

By meticulously going through these steps, we created a robust Design System that not only solved MWH's immediate challenges but also laid a sustainable foundation for future growth and scalability.
Results
For MWH, we created two distinct but harmonious Design Systems: one for the web and one for mobile. Both systems are designed to be similar but uniquely tailored to their respective platforms, making management across these platforms efficient while providing a consistent and familiar user experience.

A Design System is not a one-time project but a living, evolving entity. As MWH grows, the Design System will adapt, ensuring that it continues to meet the brand’s needs for scalability and consistency.
MWH now has a robust and sturdy foundation for scalable growth, with a Design System that’s poised to evolve alongside the brand as they work to make more mindful living accessible and attainable for all.
