Mobile App Development Services

A mobile app is the easiest kind of software to ship badly and the hardest to fix once it is sitting in the stores. We build iOS and Android products that pass review, launch on the date you announced, and keep working through the OS releases that arrive every autumn.

What you get

Mobile App Development done properly.

Three shapes of mobile product. They share a codebase strategy and almost nothing else.

Common failure modes

Where this usually goes wrong.

Named up front, because avoiding them is most of the value.

How we work

The engagement, phase by phase.

Every phase is run by senior engineers and ends in something you can see.

01

Mobile strategy

What the app is for, who has to adopt it, and which native capability actually justifies an app instead of a responsive site.

02

Platform decision

Native, cross-platform or web, argued against your roadmap and budget rather than our preference — and recorded with the trade-off attached.

03

Flows and design

Screen-by-screen flows and a design system sized for real devices, so the build starts from settled decisions instead of open questions.

04

Build in sprints

Whole features each sprint, on TestFlight and an internal Android track from the first one, so you are using the app while it is still being written.

05

Test on real hardware

Automated regression plus manual passes across the device and OS matrix your users actually carry, including the older phones that are easy to forget.

06

Launch and keep alive

Listings, review compliance, staged rollout and crash monitoring — then the annual OS cycle that decides how long the app lasts.

Proof

Shipped, and still running today.

Three mobile products in production, each solving a different distribution problem.

FAQ

Questions we get asked.

Should we build native or cross-platform?

It depends how much of the product is genuinely platform-specific. Heavy camera, Bluetooth, background location or platform-native UI work usually pays for native. A form-and-list product that has to reach both stores quickly usually does not. We make the call with your roadmap in front of us and write down the trade-off, because reversing it later is expensive. Our post on native versus cross-platform apps goes through the reasoning in more depth.

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

Yes — submission, listing copy, screenshots, privacy declarations and responses to reviewers are part of delivery. We work inside your developer accounts rather than ours, which means the app, its signing identity and its reviews stay yours if you ever change vendor.

Who owns the code?

You do. Source, repositories, build pipelines and infrastructure accounts are yours and are handed over at the end of the engagement. We do not keep client products parked in our own accounts.

Can you take over an app somebody else built?

Often, and we will say plainly when the answer is no. It starts with an assessment of the codebase, the build pipeline and the store accounts, after which you get a written view of what is worth keeping and what is cheaper to replace.

How much does a mobile app cost?

Too much rides on scope for a number here to be honest. Roles, integrations, offline behaviour and how much design already exists move the figure far more than the choice of platform does. Our consultation page sets out the six factors that drive it, and a call turns them into a range for your requirements.

What happens after launch?

OS releases, dependency updates, crash triage and store policy changes carry on regardless. Either we keep a maintenance engagement running, or you take over an app documented well enough for your own team to maintain. Budgeting nothing is the one option that reliably fails.
