Mobile Apps

Mobile app development

We build responsive, native-feeling mobile applications with offline-first synchronization, push notifications, and seamless connections to your backend AI services.

Overview

How we approach Mobile app development.

Cross-platform mobile development is mostly a set of decisions that are cheap to make early and expensive to change later: what the app does with no connection, how state is stored on the device, how notifications are routed and deep-linked, and how updates reach users without a store review every time. We build React Native and Expo applications with those decisions made deliberately.

Offline behaviour is the one that most often gets deferred. We treat the device as the source of truth for the session: writes go to local storage immediately, a sync layer reconciles with the server when connectivity returns, and conflicts resolve by an explicit rule rather than by whichever request happened to arrive last. Users on a job site with one bar do not lose work.

Push notifications are a delivery pipeline, not a feature toggle. Tokens have to be registered, refreshed, and cleaned up; payloads need to deep-link into the right screen with the right state; permissions have to be requested at a moment when the user understands why. We build and test that whole path, including what happens when the app is closed.

Release engineering is part of the work. App Store and Play Console setup, signing credentials, staged rollout, over-the-air updates for JavaScript-only changes, and crash reporting wired to real stack traces, so a bug reported by a user can be traced to a line of code rather than reproduced by guesswork.

What We Deliver

  • Cross-platform React Native / Expo apps
  • Offline-first SQLite data synchronization
  • Push notifications via Firebase (FCM)
  • Apple App Store & Google Play delivery
Delivery Methodology

How we build and deploy.

Structured engagement from initial process audit to live production monitoring.

01

Platform and data model decisions

We settle offline behaviour, local storage, sync strategy, and notification routing before building screens, because these choices shape everything above them.

02

Core application build

Navigation, screens, and state built against the real API, with the same components running on iOS and Android from one codebase.

03

Device integration

Push notifications, camera and file access, background sync, and deep links, tested on physical devices rather than only in a simulator.

04

Store submission and release

Signing, store listings, review-guideline compliance, staged rollout, crash reporting, and an over-the-air update channel for fast JavaScript fixes.

Problems Solved

Operational challenges we eliminate.

The Bottleneck

The app is unusable the moment connectivity drops

Our Solution

We rebuild the data layer offline-first: local writes, a durable sync queue, and defined conflict resolution, so poor connectivity degrades the experience instead of breaking it.

The Bottleneck

Push notifications arrive inconsistently or open the wrong screen

Our Solution

We fix the whole path: token registration and refresh, payload structure, deep-link routing, and permission timing, then verify delivery across app states on real devices.

The Bottleneck

Every small fix means another store review cycle

Our Solution

We separate JavaScript changes from native ones and ship the former over the air, cutting the turnaround on most fixes from days to minutes.

Technical Depth

Under the hood.

Deep architectural rigor built for software engineers and technical decision-makers.

Offline-first data layer

Local SQLite or MMKV storage with a queued sync layer and explicit conflict resolution, so the app stays usable with no connection and reconciles cleanly when one returns.

Push delivery end to end

Firebase Cloud Messaging and APNs with token lifecycle handling, deep-linked payloads, and delivery tested in foreground, background, and terminated states.

Over-the-air updates

JavaScript-layer fixes ship through an update channel in minutes instead of waiting on a store review, with native releases reserved for native changes.

Real crash visibility

Source-mapped crash reporting so a production stack trace points at the actual line, not a minified bundle offset.

Common Use Cases

Where this applies.

Field and frontline apps

Applications used away from reliable connectivity, where offline capture and later sync are the core requirement rather than an edge case.

Companion apps for an existing platform

A mobile client for a web product you already run, sharing the same API and authentication.

Notification-driven workflows

Apps where the push notification is the product surface: alerts that need acting on quickly, deep-linked into the exact task.

AI features on mobile

Voice capture, document scanning, and assistant interfaces connected to a backend model service with sensible latency and cost handling.

Frequently Asked Questions

Common questions about Mobile app development.

Q.React Native or fully native?

React Native for the large majority of business applications: one codebase, one team, and near-native performance for standard interfaces. Fully native where the product depends on heavy graphics, tight hardware integration, or platform features with no reliable bridge. We recommend based on the product, not on what is convenient for us.

Q.Do you handle App Store and Play Store submission?

Yes. Store listings, signing credentials, review-guideline compliance, and staged rollout are part of delivery. You own both developer accounts.

Q.Can the app work without an internet connection?

Yes, and we design for it from the start when the use case calls for it. Local storage, a sync queue, and explicit conflict rules mean work continues offline and reconciles when connectivity returns.

Q.Can you add a mobile app to our existing web product?

Usually yes. If your platform already exposes an API, the app consumes it directly. If it does not, we build the API layer as part of the project.
