Serenity: adapting a wellness app from France to Brazil
Serenity is a cultural adaptation exercise done as a team: adapting a wellness treatment booking app from France to Brazil.

- UX/UI Design
- Mobile app
- Cross-cultural design
Result
We delivered two versions of the screens, France and Brazil: home, selection, booking, payment and confirmation. Brazil adds a group flow, payment in 10 installments and loyalty points.
The project in detail
Context
A cultural adaptation exercise done as a team in 2025, over 1–2 weeks. We started from the mockups of an earlier project in French, with its own identity, designed for the Western world. It wasn't commissioned by a brand.
Problem: How do you launch this app in another country? We picked Brazil. A plain translation isn't enough: lifestyle and culture change how people book, pay and feel welcome. Our analysis showed two things: in Brazil, paying in installments, up to 30, comes naturally. And apps and sites use bright colors, with joyful people.
Key decision
Go beyond translation. We adapted the identity, the flows and the payment to local habits: bright colors, treatments for groups, payment in installments, loyalty points. These choices come from our analysis.
Approach
- Starting point: the French app “Serenity”, luxury treatments, with a cream and black identity, muted spa photos and a quiet tone.
- Analysis: we started from a comparison between Brazil and France, using the Country Comparison tool by The Culture Factor (theculturefactor.com). Individualism is lower in Brazil (36 versus 74): this guided the group treatments. Long-term orientation is lower too (28 versus 60): this fits payment in installments and low savings.
- Identity: our analysis showed that Brazilian apps and sites use bright colors, which suggest joy, and visuals of joyful people. So “Serenidade” moves to bright blue and green, with a lively home photo. Everything is translated into Portuguese, with prices in reais (R$).
- Group flow: the “Juntar a um grupo” section offers treatments for several people. A screen lets users invite friends and send them a message.
- Payment and loyalty: our analysis showed that paying in installments, up to 30 in Brazil, comes naturally. The culture looks more to the present moment than to what comes after, and savings are rather low. So “Pagar em 10 vezes” adds this payment. The confirmation gives “+ 20 pontos” with a festive illustration.






What it shows
I can adapt a product to another culture without stopping at translation: identity, flows, payment and loyalty change with local habits.
Learnings
I learned that adapting means choosing what changes and what stays. How people book, alone or with others, payment habits and tone matter as much as language.
