FIT for LIVET
A leading Danish medical weight loss clinic moved off a rented white-label app onto a bespoke Flutter platform they own — medication tracking, weight-loss projections and a recipe community.

Flutter Development
One codebase. Two stores. No compromise on native feel.
Most UK agencies reach for React Native. We reach for Flutter, and we have the shipped products to argue the case — consumer apps, clinical apps, field-operations apps, and a point-of-sale app running on physical payment hardware.
Flutter gives us a single Dart codebase compiled ahead-of-time to native ARM for both platforms, which means one team, one test suite and one release cadence instead of two of everything. That is usually the difference between a mobile product that stays current and one that quietly falls behind on one platform.
Capabilities
What we build with Flutter
Consumer apps at store quality
Full App Store and Google Play releases with staged rollouts, in-app update flows and crash-free-rate monitoring from day one.
Offline-first field apps
Hive-backed local databases with sync-on-reconnect, built for drivers and field teams who lose signal mid-shift and cannot lose work.
Hardware and payments
Thermal printer and card-reader integration on Sunmi point-of-sale handhelds, plus in-app Stripe card payments where the flow stays in the app.
Real-time and streaming
WebSocket audio streaming for live transcription, and SignalR clients receiving push events straight from a .NET backend.
Health platform integration
Apple HealthKit and Google Health Connect for activity and measurement data, with the permission handling that makes clinical review pass.
Shared component libraries
A private Flutter component package consumed across multiple apps by git reference, so a design change lands once and propagates.

Engineering Practice
How we work in Flutter
Choosing the stack is the easy part. These are the decisions that determine whether the codebase is still maintainable after we hand it over — and they are the same on every Flutter project we run.
Our certificationsThree build flavours as standard — dev, staging and production — each with its own bundle identifier, Firebase project and environment file, so a tester can hold all three on one handset.
API clients are generated from the backend's OpenAPI schema rather than hand-written, which means a breaking backend change fails the mobile build instead of reaching a user.
Typed environment configuration via envied and code generation, so no secret is ever compiled into a committed source file.
Bitrise pipelines handle signing and store submission, so a release is a button rather than an afternoon on somebody's laptop.
Crashlytics and Firebase Analytics wired per flavour from the first build, so the crash-free rate is a number we watch rather than one we discover.
