UX/UI design for health tech & wellness

Helping your digital product blend naturally into the daily routine

What we do

We build healthcare and wellness products, shape the vision behind them, and activate it through motion, storytelling, and human-focused design

O0-made brands are on Time’s 100 Best Inventions. Apps we design consistently feature in the App Store spotlight. The companies we work with are biotech unicorns, revolutionizing the future of healthcare. That’s the impact we aim for. What about you?

Discovery

During the discovery phase, we conduct in-depth interviews with users to map their health journeys, uncover pain points, and identify unmet needs. Combined with expert insights and healthcare data, this research reveals the narrative scenario with the greatest potential impact.

Brand identity and strategy

Health tech and wellness branding goes beyond logos, color palettes, and trendy graphics. We translate complex science into clear, actionable insights, helping people turn knowledge into simple, practical habits they can actually integrate into daily life.

UI/UX design

We know the ins and outs of handheld interactions and create mobile experiences that feel simple, natural, and effortless. Our partners call us picky, meticulous, and detail-obsessed — we take that as a compliment.

Development & ongoing scaling

O0-designed digital and mobile products are intuitive, enjoyable, and visually striking. Under the hood, they’re just as robust. Most importantly, we play the long game — your product or website receives regular updates, rapid feature rollouts, and seamless integrations to ensure peak performance.

Film & motion

Do you need to break down science-based concepts into bite-sized pieces? Do you want to pitch your product without losing your audience? We craft smart, engaging animations that cut through the noise and make every detail clear.

Wellness as a service (WaaS)

WaaS harnesses data analytics, machine learning, and user-centric design to deliver personalized wellness plans, actionable insights, and real-time health monitoring. From fertility tracking to decoding the gut microbiome, we create products that turn complexity into clarity. The common thread? Interfaces that are simple, empathetic, and sleek.

medical devices

Medical technology turns breakthroughs in science into solutions people can rely on. Bionic limbs, home treatment devices, and other innovations need to be clear, trusted, and understood. We craft brands, websites, and explainer videos that make advanced technology feel approachable, showing not just how it works, but why it matters.

Trainings and fitness

Can design actually motivate you to exercise? Absolutely — if it’s catchy, actionable, and never intimidating. That’s the kind of experience we create. From lively animations to intuitive dashboards and fully built-from-scratch brands, every detail keeps users engaged. The bottom line: we put the ‘fun’ back in functional.
