UpKarty — Your Benefits, One App Away

The Client

UpBonus – Employee Benefits Made Simple

UpBonus, part of the international UP group, is a leading provider of employee benefit solutions in Poland. Known for their lunch and gift cards, they came to us with a bold mission: bring all their offerings into one seamless mobile experience. 

The Challenge

One App to Rule All Cards

UpBonus needed more than just another app — they wanted a centralized, secure, and user-friendly digital wallet for all their benefit cards. The goal was to replace clutter and confusion with clarity and control, while also unlocking exclusive offers and perks.

The Process

Strategy-Fueled Design from Day One

Our journey started with a collaborative UX Strategy Workshop where we worked hand-in-hand with UpBonus stakeholders. The goal: shape a product vision that married business goals with user needs.

We mapped out user flows, prioritized core functionalities, and established a structure built for clarity and ease of use. With a solid foundation in place, we transitioned into wireframing and prototyping — validating ideas, refining interactions, and iterating toward a polished, user-first design.

Key Feature #1

Card Management Made Simple

From checking balances and transaction history to blocking lost cards and changing PINs, users have full control over their cards, anytime and anywhere.

On the backend, we leveraged Next.js 14+ with server components to handle secure data fetching and dynamic content rendering without bloating the client side. Biometric authentication on mobile provided a fast, frictionless login experience, while Przelewy24 integration ensured safe and seamless top-ups and transactions.

Key Feature #2

Exclusive Offers at Your Fingertips

A dedicated section brings exclusive deals and promo codes into the spotlight. Users can explore, activate, and purchase offers directly in the app, with all details logged for easy access.

Thanks to the component reusability strategy across platforms (React Native for mobile and Next.js on web), we maintained a consistent design and experience — making it intuitive to browse and redeem offers whether users are on the go or at their desk.

Key Feature #3

Interactive Partner Map

Finding where to use your benefits just got easier. The map filters by category (like restaurants or cinemas) and uses a search engine to pinpoint locations — whether you're nearby or planning ahead.

To power this, we integrated Google Maps and implemented real-time geolocation, allowing users to view their position and nearby partners instantly. One technical challenge was ensuring performance and minimizing API hits — which we solved by building a custom search layer with MeiliSearch, caching and indexing partner location data locally for lightning-fast lookups and smoother map interactions.
