The client needed to turn fragmented fitness, nutrition, and grocery-delivery experiences into one continuous customer journey. Users had to manually interpret calories burned, decide what to eat after training, search for suitable products, rebuild grocery carts, and complete checkout in separate applications.

The platform had to process sensitive health and dietary data, isolate every user’s records, comply with Apple and Google health-data policies, support inconsistent workout measurements, and integrate with delivery providers that use different catalog, pricing, substitution, checkout, and order-status models. Every purchase required explicit user approval.
Osambit designed a mobile-first LangGraph agent architecture combining deterministic health rules, personalized AI recommendations, persistent user memory, and human-approved checkout.
Device-side HealthKit and Health Connect ingestion minimizes sensitive data exposure, while provider adapters support catalog search, pricing, substitutions, Stripe payments, and delivery tracking.
