Mobile App Development

Mobile App Development for iOS and Android

We build native and cross-platform mobile applications that users love — from MVP to App Store launch to ongoing iteration. Every app is fast, secure, and designed around real user behaviour.

What's included

Everything delivered. Nothing left out.

iOS app development

Native Swift development for iPhone and iPad — full access to Apple APIs, Face ID, push notifications, and App Store submission.

Android app development

Native Kotlin development for Android — optimised for the full range of Android devices and Google Play submission.

Cross-platform development

One codebase for both platforms using Flutter or React Native — 80% faster to build without sacrificing quality or performance.

UI/UX design for mobile

Human-centred mobile UX design — information architecture, user flows, Figma prototypes, and usability testing before development begins.

Backend API + real-time features

We build the backend your app needs — user authentication, push notifications, WebSocket real-time updates, and third-party integrations.

Offline mode & local storage

Apps that work without a connection and sync intelligently when reconnected — critical for field teams, healthcare, and logistics apps.

App Store & Play Store submission

We handle the entire submission process — screenshots, metadata, review guidelines, and rejection resolution if it occurs.

Analytics & crash reporting

Firebase Analytics, Sentry crash reporting, and custom event tracking so you know exactly how users interact with your app.

Post-launch updates

Ongoing iteration support, OS version compatibility updates, and feature sprints after your initial launch.

Our approach

How we work

Our process is built around clarity, speed, and accountability — at every stage.

01

UX-first, then code

We start every mobile project with a detailed user flow mapping session. Before designing a single screen, we understand how users will move through the app. This shapes every subsequent decision and prevents expensive architectural mistakes.

02

Rapid prototyping and real-device testing

You get an interactive Figma prototype within the first two weeks. We test on real iOS and Android devices throughout — not just simulators — so you see exactly what your users will experience.

03

Store launch and beyond

App submission is just the beginning. We monitor crash reports, analyse user behaviour, respond to store reviews, and iterate on the product alongside you. Most of our mobile clients stay on a monthly retainer for continued development.

Who it's for

Built for teams like yours

Founders launching a consumer app

You have an idea for a mobile product and need an experienced team to take it from concept to the App Store and Play Store — fast, without cutting corners on UX.

Businesses digitising operations

You need a mobile app for your field team, warehouse, or customer-facing service. We build apps that integrate with your existing systems and work reliably in the field.

Product companies extending to mobile

You have a web platform and your users are asking for a mobile app. We build companion apps that share your backend and deliver a native experience on both iOS and Android.

FAQ

Common questions

Cross-platform (Flutter or React Native) is right for most projects — it cuts build time by up to 60% with near-native performance. Native Swift/Kotlin makes sense when you need deep OS integration, advanced graphics, or performance-critical features like real-time AR. We'll recommend the right choice after understanding your requirements.
