How we charted it

The challenge

Care plans lived in a portal nobody opened. Meridian needed a mobile app patients would actually use — one that stayed correct even on a hospital basement connection.

Our approach

  1. 01

    Built one React Native codebase for iOS and Android with an offline-first data layer that syncs cleanly when connectivity returns.

  2. 02

    Mapped clinical data to FHIR so the app speaks the same language as Meridian's records system.

  3. 03

    Shipped behind feature flags with store-release pipelines, so new features reach users weekly.

The outcome

The companion launched to a 4.8-star average across both stores, with daily active use far above the old portal and zero data-integrity incidents.

Why this stack

Expo for fast store releases, a typed GraphQL contract, and an offline queue that treats the network as optional, not assumed.
