Mobile App Development for Dublin Businesses

A technology business in Dublin, Ireland, retired its manual paper workflow in favour of a bespoke mobile app. With field teams updating records in real time and the office watching live, the firm eliminated the data-entry errors that had been costing it hours every week.

Native or Cross-Platform — How We Choose

The first decision on any mobile project is whether to build natively or share a codebase across platforms. Native means Swift for iOS and Kotlin for Android — two separate apps, each tuned to its platform. Cross-platform means one codebase, usually React Native or Flutter, that ships to both stores. There is no universally correct answer, only the right answer for your product, your budget and your timeline.

We default to React Native for most projects because it shares the majority of the codebase between iOS and Android while still compiling down to real native UI components, not a web view wrapped in an app shell. That keeps the experience fast and familiar to users, and it roughly halves the cost of building and maintaining two apps. Where a project leans heavily on platform-specific hardware, intensive graphics, real-time audio or video processing, or sub-frame animation, we will recommend going fully native instead.

What we do not do is pick a stack before we understand the problem. If your app is essentially a content and transaction layer over an API, cross-platform is almost always the better economic call. If it is a camera-first, sensor-heavy or performance-critical product, we will tell you when native is worth the extra investment rather than forcing everything through one tool.

What We Build and Who It's For

Mobile work falls into a few recognisable shapes, and most briefs we receive are a variation on one of them. Consumer-facing apps need to win attention in seconds and earn a place on a crowded home screen — booking, loyalty, content and commerce apps live or die on first impressions and friction. Internal tools have the opposite pressure: the audience is captive, so the job is to remove busywork, work reliably offline and sync cleanly when a connection returns. Marketplaces sit between the two, balancing supply-side and demand-side experiences in a single product.

Across all of these, the recurring client problems are similar. Field teams stuck on paper or spreadsheets that never reach the office in time. A web product that customers keep asking for on their phones. A manual process that does not survive contact with a small screen. The solution is rarely just "an app" — it is a considered flow that respects how people actually use a phone: one-handed, distracted, often with patchy signal.

The Stack and What Is Included

Our typical build is React Native with Expo for fast iteration and over-the-air updates, dropping into native modules in Swift or Kotlin wherever we need direct access to platform capabilities the framework does not expose. On the device side that covers push notifications, secure local storage, biometric authentication, camera and location. Behind the app sits a backend and API — either one we build for you or an integration with systems you already run — so the app is never just a pretty front end with nowhere to send its data.

Every engagement is scoped end to end rather than handed over half-finished. A standard project includes the work below, and we are explicit up front about anything that sits outside the agreed scope so there are no surprises at launch.

• UX design and an interactive prototype before any production code is written
• A cross-platform build covering both iOS and Android from one codebase
• Backend, API and data integration with the systems you already use
• Push notifications, offline support and secure authentication
• App Store and Play Store account setup, listing and submission
• Post-launch monitoring, crash reporting and an agreed update cadence

Review, Release and Timeline

Getting an app live is its own discipline. Both Apple and Google review every submission, and each has rules that catch teams out — privacy disclosures, account-deletion requirements, sign-in options, payment policies and metadata standards. We prepare your store listings, complete the privacy and data declarations, handle code signing and provisioning, and manage the back-and-forth with reviewers if anything is queried. Apple review typically takes a day or two; Google is usually faster but can hold new developer accounts for longer. We plan releases with that variability built in rather than promising a date the stores do not control.

As a rough guide, a focused first version takes around eight to fourteen weeks from kick-off to store, depending on the number of screens, the depth of backend work and how many native integrations are involved. Simpler internal tools land at the shorter end; consumer apps with accounts, payments and real-time features sit at the longer end. We work in stages so you see something running early and can steer the build before it hardens.

Finally, an honest filter: not every idea needs a native app. If your users will reach you mostly through a browser, if discovery matters more than re-engagement, or if you do not need offline access, push or device hardware, a progressive web app or a well-built responsive web app will serve you better and cost far less to maintain. We will say so when that is the case — the goal is the right product, not the most expensive one.
