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.

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.
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

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.
Ways to work together
Model A
Fixed scope, fixed price
The scope is written down in detail before work starts, and the price is fixed against it. Changes are quoted separately as they come up.
Best for: Well-understood projects — a website, a defined module, a rebuild.
Model B
Monthly retained team
An agreed number of developer days each month, directed by your priorities. Scope can move without renegotiating a contract.
Best for: Products that will keep evolving after the first release.
Model C
Phased delivery
The system is split into phases that each ship something usable. Every phase is quoted before it begins.
Best for: Large ERP, SaaS and platform builds where the full scope is big.
Model D
Support and maintenance
Ongoing care for a system that already exists — ours or someone else’s — covering fixes, updates and small enhancements.
Best for: Live systems that need a reliable pair of hands.
Sectors we apply this in
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.
