New to React Native app development?

What is React Native app development?

React Native builds native iOS and Android apps from one codebase written with React.

We build customer, field and employee apps, publish them to the stores, and upgrade older React Native apps.

Work runs as a fixed-scope project, a dedicated team or React Native engineers who join your team.

Starting point

Where are you with React Native?

What does your mobile app look like today?

  1. Path 01Nothing built yet

    A new React Native app

    You need an iOS and Android app and want one team and one codebase.

    • Started on Expo and the New Architecture
    • Screens and navigation planned first
    • Store accounts and release process set up early
  2. Path 02We inherited an app

    Taking over an existing app

    An agency or former team built it, and releases have stalled.

    • Code, library and build review
    • Release pipeline rebuilt with EAS
    • A written report and a plan
  3. Path 03It is out of date

    Upgrading or modernizing

    The app runs on the Legacy Architecture, an old version, Cordova or Ionic.

    • Libraries checked for New Architecture support
    • Version stepped up release by release
    • Web-view screens rebuilt in React Native

A mobile app on a supported version that ships updates on a steady schedule

Upgrades

Do we have to move to the New Architecture?

TodayReact Native on the Legacy Architecture, or a Cordova or Ionic app
  • New Architecture

    Migrate from the Legacy Architecture

    Update native modules and replace libraries that never moved, then upgrade past 0.82.

    Required for React Native 0.82 and every later release.

  • A supported version

    Catch up on releases

    Step the app through each version to one of the latest three minors, testing on real devices.

    Only the latest three minor versions get fixes.

  • React Native

    Move from Cordova or Ionic

    Rebuild the app in React Native and Expo, screen by screen, reusing your APIs.

    Fits web-view apps that feel slow or need more native features.

Engagement

How can you work with our React Native engineers?

    • SynconAI directs the work to agreed milestones
    • Billed by milestone, as set out in the proposal
    • A released app, tests and documentation
    • Fits a first release, a rewrite or an upgrade
  2. Dedicated team

    • You set priorities, our lead runs the team
    • Billed monthly for the team
    • Engineers, a lead and testing as needed
    • Fits an app with regular releases
  3. Team extension

Process

How does a React Native engagement start?

Five steps from the first call to an app in users' hands.

  1. Brief
    • Call about your app and users
    • Repository access or a written scope
  2. Match or design
    • Engineers matched to your app
    • Plan and proposal in writing
  3. Start
    • NDA, store and repository access
    • Codebase walkthrough and a first task
  4. Build and review
    • Test builds on real devices
    • Demos and code review with your team
  5. Hand over or continue
    • Store release and a handover session
    • Or a monthly plan for ongoing releases

Cost and timing

What it costs and how long it takes

The review is free

A 60-minute architecture review of your React Native app setup, with a written plan you keep.

A fixed-scope proposal first

Before any work starts you get a written proposal: a fixed-scope project with milestones, or a monthly plan. You approve it, or you do not.

Timing follows scope

How long it takes depends on what is in scope. The proposal states the milestones, so you see the timeline before you commit.
