Mobile App Development

Apps that earn their place on the home screen

A mobile app competes with every other icon on the device. We build for the constraints that actually decide whether it gets opened twice: launch speed, offline behaviour, battery, and a first session that explains itself.

Typically the right fit when

  • Products whose users are primarily on a phone
  • Teams choosing between native and cross-platform
  • Existing apps with poor ratings or retention

What you get from us

Judgement first, code second

The decisions made in week one determine what the app costs for the next three years.

  • The right platform strategy

    We recommend native or cross-platform based on your feature set and budget, and we explain the trade-off rather than defaulting to whichever is faster for us.

  • Built for real conditions

    Patchy connectivity, older devices and background restrictions are tested during development, not discovered in your reviews.

  • Store submission handled

    Listing assets, review guidelines, privacy disclosures and the back-and-forth with app review are part of the engagement.

  • Instrumented from day one

    Crash reporting and funnel analytics ship with the first release, so the second release is informed by data instead of opinion.

The first decision

Native or cross-platform?

There is no universally correct answer, and any agency that gives you one without seeing your feature list is telling you what suits them. Here is how we reason about it.

Device capability

Native

Full access on day one, including new OS features the moment they ship.

Cross-platform

Most capability is covered; niche or brand-new APIs may need a native module.

Cost of two platforms

Native

Two codebases, so roughly 1.7–2× the build and maintenance effort.

Cross-platform

One codebase covering both, typically 55–70% of the native cost.

Interface feel

Native

Platform-idiomatic by default — gestures and transitions match the OS exactly.

Cross-platform

Very close for standard patterns; heavily custom motion takes extra work.

Performance ceiling

Native

Highest. The right choice for real-time graphics or sustained processing.

Cross-platform

More than sufficient for content, commerce and workflow applications.

Hiring and handover

Native

Needs Swift and Kotlin skills in-house to maintain independently.

Cross-platform

A single JavaScript or Dart team can own the whole product.

In practice most products we scope land on cross-platform, and we say so when they do. We recommend native when the feature list genuinely requires it — not as an upsell.

Capabilities

What we build for mobile

Whole products, or a specific piece of one — store presence, messaging and instrumentation are all scopeable on their own.

  • 01

    iOS development

    Native Swift applications for iPhone and iPad that follow current Apple interface conventions.

  • 02

    Android development

    Kotlin applications built against Material guidelines and the realities of device fragmentation.

  • 03

    Cross-platform builds

    React Native and Flutter apps sharing one codebase where the feature set genuinely allows it.

  • 04

    App store optimisation

    Listing copy, keywords, screenshots and release sequencing planned for discoverability.

  • 05

    Push & lifecycle messaging

    Segmented notifications that bring users back without training them to disable alerts.

  • 06

    Mobile analytics

    Event tracking, retention cohorts and crash monitoring wired to dashboards you can read.

Stack

Whichever platform the decision lands on

We work across both native toolchains and the two mature cross-platform frameworks, which is what makes the recommendation an honest one.

Store submission, signing and release management are handled as part of the engagement rather than left with your team.

  • React Native
  • Flutter
  • Swift
  • Kotlin
  • iOS
  • Android
  • Firebase
  • PWA

How it runs

You are using the app long before launch

Internal builds go out continuously, so nobody is waiting until the end to find out how it feels on a real device.

  1. 1

    Platform & scope decision

    1 week

    We work through your feature list, target devices and budget, then put the native-versus-cross-platform recommendation in writing.

  2. 2

    Flow design

    1–2 weeks

    Onboarding, core loop and permission prompts designed around the first ninety seconds, which is where most apps are lost.

  3. 3

    Build & internal releases

    6–12 weeks

    Regular TestFlight and Play internal builds so you are using the app on your own device throughout, not at the end.

  4. 4

    Device testing

    1–2 weeks

    Real-device testing across screen sizes and OS versions, plus offline, low-battery and interrupted-session cases.

  5. 5

    Submission & launch

    1–2 weeks

    Store listings prepared, review responses handled, and a staged rollout with crash monitoring in place.

Deliverables

What you actually receive

Including the operational pieces most app projects forget until the first bad release.

  • Source repository for each platform
  • Signed builds and store listings
  • Analytics and crash reporting setup
  • Device and OS support matrix
  • Release and rollback procedure
  • Post-launch monitoring dashboard

Questions

Before you get in touch

Should we build native or cross-platform?

It depends on how much of your app touches platform-specific capability. Heavy camera, Bluetooth, background processing or platform-idiomatic interaction favours native. Content, commerce and workflow apps are usually well served by React Native or Flutter at meaningfully lower cost. We make the call with you in the first week.

Do you handle App Store and Play Store submission?

Yes. That includes listing assets, privacy and data-use disclosures, age ratings, and responding to review feedback until the app is live.

Can you take over an app another team built?

Usually. We begin with an audit covering dependency health, build reproducibility and crash data, then give you an honest read on whether continuing is cheaper than restarting.

Will the app work offline?

If your users need it to, yes — and we will raise it in scoping if we think they do. Local caching and conflict resolution are design decisions best made early rather than bolted on.

Planning an app, or fixing one?

Tell us what it needs to do and who is meant to open it daily. We will recommend a platform and a realistic first release.

No obligation. We will tell you if we are not the right fit.
