We design fitness apps, sports platforms and wellness brands that keep people motivated. Habit-building UX, social features and calm, premium identities that drive engagement and retention.
We ARE

UI/UX and brand design for sport and wellness products

Healthy habits are hard to keep, and the product has to help. Cosmos Studio designs fitness, sport and wellness experiences around motivation and retention. Fastmates turns intermittent fasting into a social habit with fasting mates, a nearby-mates radar and playful status creatures. Remroom positions high-tech sleep rooms as a calm, premium, science-driven brand without wellness clichés. For Zeuss, a US telehealth platform for weight loss, skin and hormone therapy, our redesign led to higher conversion rates and longer sessions. We design products people come back to every day.

Remote-friendly team growing fast

Senior team, lasting results

Why Cosmos Studio

10 years. 500+ projects. Most clients stayed for years

01

Long-term partnerships

End-to-end product flows for LMS products, e-learning platforms, and education SaaS. Pixel-level craft on the surfaces your users actually touch: onboarding, dashboards, student and teacher portals, edge cases.

02

Senior-only team

Every designer has 5+ years of product design experience. No juniors on client work. Every deliverable goes through Art Director review. You don't manage quality. We do.

03

We think in product

We know what retention, onboarding drop-off, and conversion mean for design decisions. When something looks good but creates friction, we say so.

FAQ

Answered questions

1

What sport and wellness products do you design?

We design fitness and training apps, habit and nutrition trackers, sleep and recovery products, sports platforms, booking and membership flows, and brands and websites for wellness companies.
2

How do you improve retention in fitness and wellness apps?

We design around habit loops: a fast first win in onboarding, clear progress, reminders that help instead of nag, and social accountability. In Fastmates, fasting mates and a nearby-mates radar turn a solo routine into a shared one.
3

Can you create a wellness brand that doesn't look generic?

Yes. For Remroom we avoided typical wellness clichés and built a minimalist, typography-driven identity with a custom logotype and restrained palette, positioning high-tech sleep rooms as premium and science-driven.
4

Do you design for wearables and health data?

We design flows that use data from wearables and health platforms such as Apple Health and Google Fit, and we make that data readable: simple trends, clear goals and no overwhelming charts.
5

How long does a fitness app design project take?

An MVP app design usually takes 6–8 weeks, including research, flows, UI and a clickable prototype. A brand identity takes 2–5 weeks depending on scope.
6

Do you also develop the product?

Yes. Our UI engineering team builds web apps and websites with React, Next.js and TypeScript. For native mobile development we work together with trusted development partners, and Cosmos Studio stays responsible for the whole process.
