SFD: Building loyalty in the world of Mobile Commerce
A comprehensive loyalty app that combines full store functionality with gamification, boosting retention and basket value.
Who is SFD?
SFD is a leader on the Polish supplements and nutrition market. The brand grew out of a bodybuilding forum community (sfd.pl) and needed a tool to bring that community into the mobile era.
Business goal: Build a new sales channel that does not only sell, but creates a daily habit of engaging with the brand through gamification and education.
What were we up against?
- Replicating full e-commerce logic (discounts, bundles, stock levels) in a native app.
- Building an engaging challenge system (drink water, count steps) that runs smoothly in the background.
- Integrating Apple Health and Google Health Connect to automate progress tracking.
- Real-time sync with the client's existing, complex backend.
