Mobile app development for Android and iOS

Apps built to be used daily — fast to open, sensible offline and maintainable once they are in the stores.

Support after launch

The first decision on any mobile project is whether it needs to be native at all. A cross-platform build in Flutter or React Native gives you one codebase for both stores and is the right answer for most business apps. Native becomes worthwhile when the app leans heavily on platform hardware, background processing or very particular animation.

We make that call with you, in the open, based on what the app has to do — not on which framework we would prefer to write.

Problems this solves

Two codebases, twice the maintenance

Separate Android and iOS builds double the cost of every feature and every bug fix for the life of the product.

Useless without a connection

Apps used by delivery riders, field engineers or sales staff cannot assume reliable data coverage.

Store rejections

Privacy declarations, permission justifications and account deletion requirements cause avoidable delays when they are considered late.

Battery and data complaints

Aggressive polling and unoptimised images generate uninstalls faster than almost anything else.

What the work covers

Platform strategy

An honest cross-platform versus native recommendation with the reasoning shown.

Mobile UI/UX

Interfaces that respect each platform’s conventions rather than fighting them.

Cross-platform build

Flutter or React Native, sharing one codebase across Android and iOS.

Offline and sync

Local storage with conflict handling for genuinely intermittent connectivity.

Backend and APIs

The services, push notifications and authentication the app depends on.

Store submission

Builds, signing, listings, privacy declarations and release management.

Mobile delivery

Idea to store listing

The path a mobile app takes from concept to a maintained release. API integration is a stage in its own right because it is where most mobile timelines actually slip.

Idea

What the app is for and who opens it daily.

UX/UI

Flows and screens for both platforms.

Development

Shared codebase, platform-specific where needed.

API integration

Backend services, auth and push.

Testing

Real devices, offline states and OS versions.

Deployment

Store listings, signing and staged rollout.

Maintenance

OS updates, crash fixes and new releases.

What you end up with

One codebase covering both Android and iOS

Works sensibly where connectivity is poor

Store requirements handled before they cause delays

Push notifications and analytics wired in from the start

Predictable maintenance rather than two divergent apps

Builds and signing keys held in your accounts

Technologies we commonly use for this

The stack is chosen per project — from your requirements, your existing systems and who will maintain it afterwards. This list is what we reach for most often, not a fixed answer.

Frequently asked questions

Cross-platform suits most business applications — ordering, field service, booking, internal tools — and halves long-term maintenance. Native is worth the extra cost when the app depends on heavy background processing, advanced camera or sensor work, or very demanding graphics.

Yes. We prepare the builds, listings, screenshots and privacy declarations, and submit under your developer accounts so you retain ownership of the listings and signing keys.

Where the use case requires it, we store data locally and synchronise once a connection returns, with defined rules for resolving conflicting edits.

Both platforms release annual OS updates and periodically change store policy. An app that is not maintained will eventually stop being accepted for update, so budget for a modest ongoing allowance.
