App Development

Mobile App Development Company for iOS & Android

We design and build mobile apps for iOS and Android — one shared codebase, native-quality performance, and a store-ready release at the end. You get a working build to test every second Friday, so the app you launch is the app you watched take shape.

At a glance

  • One codebase for iOS and Android
  • Store listing and release handled for you
  • Clickable app prototype before any build
  • Crash reporting set up from the first beta
Why it matters

From an app idea that keeps slipping to one people actually install.

  • Two platforms, double the budget

    Separate iOS and Android teams mean two codebases, two sets of bugs and features that ship on one platform months before the other.

  • Apps that feel like websites

    Slow screens, janky scrolling and odd navigation get one-star reviews fast — and uninstalls faster. Users expect apps to feel native.

  • Stuck at the store gate

    Rejected builds, missing privacy declarations and signing problems can delay a launch by weeks when nobody on the team has shipped before.

  • One codebase, both stores

    React Native or Flutter lets one team ship iOS and Android together, with native modules wherever the platform demands it.

  • Smooth, native-feeling UX

    Platform navigation patterns, 60 fps animations and offline-aware screens — tested on real low- and mid-range devices, not only the latest phones.

  • A release you don't have to babysit

    We handle signing, store listings, privacy labels and review submissions, then set up crash reporting and analytics before launch day.

What we build

App Development services.

Whether you're validating an idea or rescuing an app that's falling behind, the work starts from the same place: what your users need to do, and the fastest reliable way to let them do it.

  • Cross-platform apps

    React Native or Flutter apps that share most of their code across iOS and Android, without giving up native performance or platform conventions.

  • iOS app development

    iPhone and iPad apps that follow Apple's Human Interface Guidelines, with Swift modules for anything the cross-platform layer can't do well.

  • Android app development

    Apps that behave well across the long tail of Android devices and screen sizes, with Kotlin modules where they're needed.

  • MVPs for startups

    A focused first version that tests your riskiest assumption with real users — scoped to weeks, not quarters, and built to grow rather than be thrown away.

  • App modernization & rescue

    Inherited an unstable app? We audit the codebase, stabilise crashes, upgrade outdated dependencies and set out a plan to move it forward.

  • Backend, admin & APIs

    The parts users never see: APIs, authentication, push notifications, payments and an admin panel so your team can run the product day to day.

Our process

How we deliver App Development.

Five stages with fixed deliverables at each one. Timelines below are typical for a first release; a focused MVP is often shorter.

  1. 01

    Discover

    Week 1 — 2

    We map your users, the jobs they need the app for and the riskiest assumptions, then agree what the first release must — and must not — include.

    • User flows
    • Feature scope
    • Technical approach
  2. 02

    Design

    Week 2 — 4

    Wireframes become a clickable prototype you can put in front of users on a real phone before any production code is written.

    • Clickable prototype
    • UI design
    • Design system
  3. 03

    Build

    Week 4 — 12

    Two-week sprints with a TestFlight / internal-testing build every second Friday. API, app and admin panel move forward together.

    • Test builds
    • API & admin
    • Automated tests
  4. 04

    Launch

    Week 12 — 14

    Device testing, store listings, privacy declarations and submission. Crash reporting and analytics are live before the first user installs.

    • Store submission
    • Crash reporting
    • Analytics
  5. 05

    Scale

    Ongoing

    OS updates, new features and improvements driven by real usage data and store reviews — on a retainer or with a dedicated team.

    • OS-update support
    • Feature roadmap
    • Performance tuning
Technology

The stack we use.

We pick the stack for the product, not the other way round. These are the tools we reach for most often on mobile projects.

  • React

    React Native shares skills and code with the web

  • Flutter

    pixel-consistent UI across platforms

  • TypeScript

    fewer runtime surprises in large apps

  • Node.js

    APIs and real-time features

  • PostgreSQL

    reliable relational data

  • Supabase

    auth and data for fast MVPs

  • Figma

    prototypes users can tap through

  • Swift & Kotlin

    native modules when the platform demands it

Engagement & pricing

Pricing an app, three ways.

Most first app versions fit a fixed scope. Products that keep shipping features move to a monthly team.

  • First release and MVP apps

    Fixed scope

    We agree the screens and features, then fix the price for the first store release, paid in milestones.

  • Apps with a busy roadmap

    Dedicated team

    Your own app squad each month — new features, store updates and analytics reviews on your priorities.

  • Live apps that need care

    Retainer

    OS updates, store policy changes, crash fixes and small improvements inside a monthly block of hours.

FAQ

App Development: common questions

How much does it cost to build a mobile app?

It depends on scope more than anything else: the number of screens, integrations (payments, maps, chat), whether you need an admin panel, and how polished the first release must be. A focused MVP costs far less than a full product. After a short discovery call we give you a fixed quote for the first release, broken down by stage.

How long does app development take?

A focused MVP typically takes 8–12 weeks from kickoff to store submission; larger products take longer and are usually released in stages. You see a working test build every second Friday, so progress is never a mystery.

Should we build native or cross-platform?

For most business apps, cross-platform (React Native or Flutter) is the better choice: one codebase, one team, both stores. We recommend fully native only when an app depends heavily on platform-specific capabilities — and even then we usually mix in native modules rather than building twice.

Do you publish the app to the App Store and Google Play?

Yes. We prepare the store listings, screenshots, privacy declarations and signing, and handle submission and reviewer questions. The apps are published under your own developer accounts so you stay in control.

Who owns the code and the app?

You do. The source code, designs and store accounts belong to you, and we work in a repository you can access from day one.

Can you take over an existing app?

Yes. We start with a short audit — code quality, crash reports, dependencies, build pipeline — and tell you honestly whether it's worth stabilising or partly rebuilding, with a plan for either.

What happens after launch?

Apps need regular care: OS updates, store policy changes, bug fixes and new features. We offer a monthly retainer or a dedicated team, depending on how fast you want to move.
