Mobile App Development
A mobile app is the visible tenth of a system. The rest is the API it talks to, the data it caches when the network drops, the background work the operating system keeps trying to kill, and the infrastructure underneath. We build all of it.
We build in Flutter, for Android and iOS from one codebase — and drop to native platform code for the parts that genuinely need it.
What we build
Screens are the easy half. These are the problems that decide whether an app survives contact with real users on real phones.
Basements, warehouses, rural routes, dead zones between towns. An app that assumes connectivity loses data in exactly the places the business needs it most. We design for capture-now, sync-later, with the queue and conflict handling that implies.
Android and iOS both aggressively suspend background work to protect battery. Long-running location or sync features need foreground services, push-based wake-ups and platform-specific handling — not just a timer that quietly stops firing.
Live updates need decisions on both sides: what pushes, what polls, what reconciles after a reconnect, and what the user sees while the two disagree.
Anything reported from a device can be manipulated. Where accuracy matters, the system has to record how confident it is in a reading — not just the reading.
Not every app needs all of this — but these are the layers that exist behind a working one.
One codebase for both platforms, with native access through platform channels where a feature needs it.
So the app keeps working when the network doesn't, and reconciles cleanly when it returns.
Structured modules, guards and dependency injection — which keeps auth and permissions manageable as the app grows.
Relational integrity for domains with real structure; caching where response time matters.
Sessions that survive app restarts without asking users to log in constantly, and revoke cleanly when they shouldn't.
Reproducible builds, automated deployment, and a repeatable path to both app stores.
Field attendance where the network can't be assumed and a GPS reading can't be taken at face value. Offline capture, a native foreground service for battery-aware background tracking, push-based wake-ups, and a confidence signal recorded alongside every location.

Visit product arrow_forwardOne codebase covering Android and iOS, without giving up access to the platform where it matters. Where a feature genuinely needs native code — a foreground location service, for instance — we drop to platform channels for that piece rather than duplicating the whole app.
Yes, and we prefer to. A mobile app is only as good as the API behind it. We build the backend, the database, the authentication and the cloud infrastructure as part of the same system.
After reviewing it. We look at the codebase, the architecture, the release setup and its current condition first, then say honestly whether taking it over, restructuring it or rebuilding parts of it is the lower-risk path.
Yes — build configuration, signing, store listings and submission for both Google Play and the App Store, plus the release process for later updates.
