Mobile App Development

Launch Your App On iOS and Android

A cross-platform MVP built from one codebase for a fixed price, tested on real devices and launched on both app stores with analytics and crash reporting in place, then improved once you know what keeps users coming back.

What you get at each stage

Sized to where your product is now, and built so the next stage adds to it rather than starting again.

  1. Idea & validation

    Decide whether you need an app yet

    • A check on whether a web app or prototype could test the idea first
    • The feature list in your brief cut down to a true MVP
    • A clickable prototype of the main flows
    • A technical plan: platforms, backend and third-party services
  2. MVP & launch

    Ship one cross-platform app to both stores

    • A cross-platform build for iOS and Android from one codebase
    • Sign-up, payments and push notifications where needed
    • Analytics and crash reporting set up before launch
    • App Store and Google Play listings and submission
  3. Growth & scale

    Scale the app around what users actually do

    • Stability and performance work guided by crash data
    • Retention features based on usage analytics
    • Backend scaling as user numbers grow
    • Native modules or a native rebuild where the product needs it

What is included

Cross-platform build

One codebase for iOS and Android, using a framework such as React Native or Flutter.

Backend and APIs

Accounts, data storage and integrations set up on managed services that can grow with you.

Product analytics

Event tracking for sign-up, activation and retention, so you can see what users actually do.

Crash reporting and testing

Crash and error reporting, plus testing on real devices before each release.

App store launch

Store listings, screenshots, privacy details and submission to the App Store and Google Play, from developer accounts in your name.

Security and privacy

Secure sign-in, encrypted connections and device permissions requested only when they are needed.

Everything in Mobile App Development

11 services. Take one or combine several: we size each to your stage and agree the scope and a fixed price before work starts.

Building the app

  • Cross-platform appsOne codebase for iOS and Android, in a framework such as React Native or Flutter.
  • Native iOS and AndroidNative apps in Swift or Kotlin, when the product depends on device features or demanding graphics.
  • Progressive web appsWeb apps that install and work like native apps, when the app stores are not needed yet.
  • API integrationYour app connected to payments, maps, sign-in and the services you rely on.
  • Push notificationsTimely, useful notifications that bring users back.
  • In-app purchasesSubscriptions and purchases set up through the app stores where their rules require it.

Launch and after

  • App store submissionListings, screenshots, privacy details and submission to the App Store and Google Play.
  • App store optimisationStore listings that help the right people find and install your app.
  • Performance optimisationFaster start-up, smoother screens and lower battery use.
  • App securityProtection for your app, your users’ data and your API.
  • Maintenance and updatesYour app kept current with new OS releases, fixes and improvements.

Scope it free, then build it

Your MVP brief is the brief

The brief you write in the free MVP builder is what we quote from. It tells us who the product is for, the Must-have features, the main journeys and the budget, so work on Mobile App Development starts from your brief, not a blank page. It fits these stages:

For established companies

New products and ventures, scoped first

Established companies use the same approach to test a new customer app, a companion app for an existing product or a pilot in a new market: a focused first version released to a limited audience, with the data to decide whether to invest further.

Questions founders ask

Should we build native or cross-platform?

For many MVPs, cross-platform makes sense: one codebase, one team and both stores. Native is worth it when the app depends heavily on device features, demanding graphics or platform-specific design. We help you decide based on what the product needs.

Do we need an app at all?

Not always. If the idea can be tested with a web app or a clickable prototype, that is usually cheaper and quicker to change. An app makes sense when people will use it on their phone every day, need it offline, or need device features such as the camera, location or notifications.

How is an app priced?

For a fixed price, agreed after a free scoping call and based on the Must-have features in your brief. The figure above is one studio’s published range, not ours. Changes are priced separately before work on them starts.

Can the app stores reject our app?

Yes. Apple and Google review apps against their own guidelines, covering things like privacy disclosures, payments, content and whether the app is complete. Digital goods sold inside an app usually have to use the store’s own billing, with exceptions that vary by country. We plan for review from the start, but approval is always the store’s decision.

Who does the development work?

Our own team. We scope the work with you from your brief and design and build it ourselves: one brief, one point of contact and no hand-offs between agencies.

Scope your MVP free. Build it with us.

Start your brief in the free MVP builder: no sign-up, and it saves on your own device as you go. When it is ready, we price it as a fixed scope and build it, with brand, company set-up and launch alongside.
