Mobile app development

Native Android and iOS applications, published and maintained

We build native mobile applications in Kotlin for Android and SwiftUI for iOS, connected to a single REST API so the business rules stay consistent everywhere. We also handle everything around the code, including store listings, review requirements, privacy declarations and the ongoing maintenance that published applications demand.

Deciding whether you need an app at all

The first honest question is whether a mobile application is the right answer, because a responsive website reaches everyone immediately, needs no download, requires no store approval and can be updated the same afternoon. A great many businesses that commission an app would have been better served by making their website work properly on a phone.

A native application genuinely earns its cost in specific circumstances. When users need it repeatedly, so the effort of installing is repaid. When notifications matter, because a push alert reaches someone in a way a website cannot. When the app must work with poor signal or no signal at all, storing work and syncing when the connection returns. When the camera, location, contacts or biometric login are central to the task. When the interface needs to be genuinely fast under heavy repeated use, such as scanning a hundred items in a warehouse.

If none of those apply, we will tell you. It is a short conversation that occasionally costs us a project and consistently earns the trust that leads to better work later.

Why we build natively

Cross platform tools have improved considerably and they suit some projects, particularly simple applications where budget is the dominant constraint. We choose native Kotlin and SwiftUI for applications that matter to a business, for reasons that show up over years rather than in the first demonstration.

Native applications start faster, feel correct on each platform because they use the platform own components, behave better on the older and cheaper devices that a large share of real users carry, and integrate with system features without waiting for an intermediate layer to catch up. They are also far less exposed when Apple or Google change their requirements, which happens every year and has repeatedly stranded applications built on abstraction layers.

One API, two applications, consistent rules

Both applications talk to the same backend through a REST API built with Django REST Framework. That is not a technical detail, it is what stops the two platforms drifting apart. When the business logic lives in one place, a rule change applies everywhere at once, and the web interface, the Android app and the iOS app cannot quietly disagree about what a record means.

This architecture also protects you commercially. The API is an asset in its own right. If you later add a partner integration, a customer portal or a completely new client application, the foundation already exists rather than needing to be extracted from inside an app.

Publishing is the beginning, not the end

Getting an application into the stores involves more than uploading a file. Each store has requirements covering privacy declarations, data handling disclosures, account deletion, permissions justification, screenshots, age ratings and content policy. Applications are rejected regularly for reasons that have nothing to do with the code, and dealing with that calmly is part of the service.

After publication the obligation continues. Both platforms raise their minimum requirements each year, and an application that is not maintained will eventually stop being accepted for updates and then stop being offered to new users. We keep published applications current, release updates in stages so a problem never reaches everyone at once, and watch crash reporting so faults are found before reviews start appearing.

Applications we build

Where mobile genuinely changes the work

Field data capture

Job sheets, inspections, deliveries and site records completed where the work happens, with photographs, signatures and location, saved locally when signal disappears and synced automatically when it returns.

Notification driven apps

Where the value is in reaching somebody promptly, such as schools alerting parents about attendance, services confirming appointments or teams being told that something needs attention now rather than tomorrow.

Customer facing apps

Account access, booking, ordering, tracking, loyalty and support in one place for customers who deal with you often enough that installing an application is worth their while.

Scanning and inventory

Barcode and code scanning for stock counts, goods received, asset checks and dispatch, where speed of repeated action is the entire point and a browser cannot compete.

Education applications

Teacher applications for fast record entry and attendance, parent applications for progress and alerts, both built around the reality that a teacher has seconds and a parent checks in the evening.

Internal staff tools

Rotas, timesheets, approvals, internal directories and communication for teams who are rarely at a computer, distributed through the stores or through managed internal distribution.

Mobile app questions

It depends on your audience. Internal applications for a known workforce can sometimes start with one platform if the devices are standardised. Public applications almost always need both, since excluding half your users is rarely acceptable. Because both share one API, adding the second platform later is cheaper than building the first.

Yours. The applications are published under your organisation accounts so you own the listings, the reviews, the analytics and the relationship with each platform. We can manage the accounts on your behalf, but ownership stays with you, which matters enormously if you ever change supplier.

Usually a few days, occasionally longer when a policy question arises. It is outside anyone control, so we prepare listings, privacy declarations and review notes carefully to reduce the chance of rejection, and we plan launch dates with review time included rather than assumed away.

There are annual developer account fees for each platform, the hosting for the backend the app talks to, and a maintenance arrangement covering compatibility updates as each platform raises its requirements. We quote all three before you commit so the second year holds no surprises.

To a degree, and it depends on the task. Recording work offline and syncing later is practical and we build it regularly for field teams. Anything requiring live shared data, such as checking current stock across a company, needs a connection. We design the offline behaviour deliberately rather than leaving it to chance.

Tell us who would use the app and how often

That single answer usually determines whether an application is worth building or whether a better mobile website would serve you for far less.
