Challenge

One of the biggest challenges was building a subscription and discount system that remains compliant with Apple's and Google's in-app purchase policies while still supporting flexible, backend-managed promo codes. Since neither store can see the discount code itself, the backend had to validate codes and select the correct pre-configured discounted SKU before handing the purchase off to RevenueCat. Designing the in-app wallet to comply with Apple's earned loyalty credit policy added another layer of care, since credits had to be clearly earned through referrals rather than purchased. Building the calculation engine to handle BMR, TDEE, and macro targets accurately across different goal types and to recalculate automatically whenever a user updates their profile required careful logic design. The recipes module also presented scale challenges, since the system needed to support an initial import of roughly ten thousand recipes with full nutritional data, filtering, and goal-based tagging. On the influencer side, keeping commission tracking accurate while excluding cancelled and refunded subscriptions, and keeping each influencer's data fully isolated from every other influencer's, required strict access control built into the portal from the start.
