What we build

Every project is different. We choose the platform and architecture that best fits your users, your budget, and your roadmap — not the one that is easiest for us.

Native iOS

iPhone & iPad Apps

Built with Swift 6.0 and SwiftUI for maximum performance and full access to Apple's hardware capabilities. We use UIKit where it matters, and extend to watchOS, tvOS, and visionOS when your product demands it. Strict concurrency, modern MVVM architecture, and thorough unit testing as standard.

Native Android

Android & Tablet Apps

Kotlin-first development with Jetpack Compose and Material Design 3. We target the full range of Android devices — phones, tablets, foldables, Wear OS, and Android TV. Coroutines for async work, Hilt for dependency injection, and Room for local persistence. Clean Architecture throughout.

Cross-Platform

Flutter Apps

A single Dart codebase that compiles to native ARM code on both iOS and Android. Flutter gives you near-native performance with significantly faster time-to-market. We use Riverpod for state management, go_router for navigation, and write platform channels when you need access to native APIs.

Cross-Platform

React Native Apps

Ideal when your team already invests in the JavaScript ecosystem. We build with the New Architecture (Fabric renderer, TurboModules), TypeScript throughout, and Expo for managed workflows. React Native bridges the gap between web and mobile, letting you share business logic across platforms.

Selected work

Real projects, real outcomes. Here are four mobile apps we have built or rebuilt for clients ranging from Series B startups to Fortune 500 corporations.

Airalo

eSIM marketplace — Series B, backed by Sequoia

Airalo is the world's largest eSIM marketplace, serving travellers in 200+ countries. We engineered core modules of the iOS application using SwiftUI with an MVVM+Combine architecture, built the eSIM activation flow that handles carrier provisioning edge cases across dozens of device models, and implemented the multi-currency purchase pipeline. The app maintains a 4.7-star App Store rating across more than 700,000 reviews.

Seenit

BBC, HSBC, Vodafone, Deloitte, Google

Seenit's user-generated video platform lets enterprises crowdsource, edit, and publish video content from employees and customers at scale. We rebuilt the iOS app from a legacy Cordova hybrid to fully native Swift, delivering a 300% improvement in video capture performance and 60fps real-time filters. We also architected the white-label system that powers 10+ custom-branded versions of the app, each with its own asset pipeline, push notification config, and App Store listing.

DeepHow

Fortune 500 manufacturers — AI-powered workforce training

DeepHow uses AI to turn expert knowledge into step-by-step video training guides for factory floors and field technicians. We developed the iOS capture and playback modules, integrated on-device Core ML models for real-time object detection during recording, and built the offline-first sync engine that works reliably in environments with poor or no connectivity. Deployed across Fortune 500 manufacturing sites, the platform has been linked to a 77% reduction in safety incidents at early-adopter facilities.

Honda UK

Dealership operations — internal tooling

An internal iPad application used daily by 500+ staff across Honda's UK dealership network. The app manages vehicle inspections, service bookings, parts ordering, and customer handover workflows. We designed it offline-first using Core Data with CloudKit sync, so technicians on the workshop floor can operate without relying on patchy dealership Wi-Fi. The interface follows Honda's corporate design system and supports barcode scanning for VIN lookups and parts identification.

How we work

Transparent, structured, and low-overhead. We integrate with your existing team and tools rather than imposing our own process on you.

Discovery & Architecture

We start with a technical discovery phase to map your requirements, define the architecture, and identify risks early. You get a detailed technical specification, timeline, and fixed-price or time-and-materials estimate before any code is written.

Iterative Development

Two-week sprints with demo builds at the end of each cycle. You see working software every fortnight, not just slide decks. We use TestFlight and Firebase App Distribution to keep stakeholders in the loop throughout.

Quality & Testing

Unit tests, integration tests, and UI tests are part of every sprint — not an afterthought. We run automated CI pipelines on every pull request and conduct manual QA on real devices across OS versions before every release.

Launch & Support

We handle App Store and Google Play submissions, including compliance reviews, screenshot generation, and ASO metadata. Post-launch, we offer ongoing maintenance, monitoring, and feature development on a retained or ad-hoc basis.
