Mobile App Development

Mobile app development services for iOS and Android

We build iOS and Android apps from one Flutter codebase, connected to the systems your business already runs on, and launch them ready to be found in both stores.

Two apps to build, one budget

Building separate native apps for iOS and Android doubles the work for every feature and every fix. Many businesses either can't justify that or end up with one platform falling behind the other.

The other common gap is everything around the app: the backend it depends on, the ERP or CRM data it shows, and the store listing that decides whether anyone installs it.

Signs this is costing you

  • You need iOS and Android but can't fund two separate apps.
  • Customers ask for an app to book, order or check status.
  • Field staff work from paper or spreadsheets that should be an app.
  • An existing app is fragile and its original developer has moved on.
  • The app launched, but few people find it in the stores.

How we approach it

  1. Step 01

    One codebase, both platforms

    Flutter runs on iOS and Android from one codebase, so features and fixes ship to both at once. If your app needs platform features Flutter handles poorly, we'll say so before you commit.

  2. Step 02

    Scope around the data

    We map every system the app reads from or writes to, and build a documented API layer so the app never talks to your ERP or CRM directly.

  3. Step 03

    Design for thumbs

    Flows and prototypes tested on real devices before development, with accessibility built in.

  4. Step 04

    Launch store-ready

    Store listings, screenshots and keywords are prepared alongside the build, and analytics are in place from the first release.

How the project runs

  1. Step 01

    Paid discovery

    Users, systems involved and a first-release scope. Credited to the build.

    You get: Scope and a fixed price

  2. Step 02

    Design

    Flows and prototype, tested with users.

    You get: Approved prototype

  3. Step 03

    Build

    Short cycles with test builds on your phone.

    You get: Working app in test

  4. Step 04

    Launch

    Store submission, listings and analytics.

    You get: Live app in both stores

How you can work with us

The first release is fixed price after discovery. After launch, most teams continue hourly or with a dedicated developer.

  • Usual fit for this service

    Fixed price

    A defined integration, workflow or first release of an app.

    Discovery produces a written plan with scope, deliverables and a fixed price. Changes to scope are quoted before they're built.

  • Hourly

    Small changes, fixes, or work that's hard to scope until someone looks at it.

    Time is logged against each task, so you can see where every hour went.

  • Monthly retainer

    Integrations and automations that are live and need someone responsible for them.

    Monitoring, fixes and small changes during business hours, Monday to Friday (PKT), with a monthly summary.

  • Dedicated developer

    Ongoing product work where you want the same engineer every day.

    One engineer works in your tools and stand-ups full time. You set the priorities.

Common questions

Something else? Ask an engineer.

Why Flutter instead of two native apps?

One Flutter codebase runs on iOS and Android, so you build, test and maintain one app instead of two. If your app depends on platform features Flutter handles poorly, we'll tell you before you commit.

How much does a mobile app cost?

Design is included. The price depends on screens, user roles and the systems the app connects to, and is fixed after paid discovery.

Do you handle App Store and Google Play submission?

Yes. We prepare the listings and submit under your developer accounts, so the app and its reviews belong to you.

Can you help people find the app after launch?

Yes. Our app store optimization service handles keywords, listings and store tests once the app is live.

Can you take over an existing app?

Yes. We start with a review of the code, backend and open issues, fix what's risky, then continue development.

Who owns the code and store accounts?

You do. The code is in your repository and the app is published under your developer accounts.
