End-to-end mobile app development across iOS, Android, React Native, and Flutter. Discovery, design, native engineering, App Store and Google Play release, and the ongoing product engineering most agencies treat as someone else's problem. Tokyo and London team, single point of accountability.
The brands that win on mobile treat the app as a continuously evolving product — instrumented, A/B tested, released on a regular cadence, and supported by an engineering team that's still around six months after launch. Most agency-built apps die quietly within a year because no one owns version 1.1. We build with the next two years in the room: clean architecture, test coverage that survives turnover, App Store release discipline, observability from day one, and a retainer model that makes ongoing iteration the default — not a separate sales conversation.
"Shipping the app is week sixteen. The actual product begins on week seventeen, and that's where most engagements end. Ours don't."
Swift, SwiftUI, UIKit, modern concurrency, Combine, and the Apple platform expertise that makes the difference between an app that feels like an app and one that feels like a wrapped website. WidgetKit, App Clips, Live Activities, and StoreKit 2 where they fit.
Kotlin, Jetpack Compose, Coroutines, the modern Android architecture stack, and material-aware UI that respects the platform. Play Console release engineering, in-app review, and Play Billing integration done correctly.
Cross-platform development with React Native and Expo for brands that need iOS and Android from one codebase without sacrificing native quality. Reanimated, Skia, native modules where required, EAS for build and OTA updates.
Flutter for brands choosing a single codebase with strong design fidelity and performant animation. Riverpod or BLoC architecture, custom rendering with Impeller, and platform-channel work for native integrations.
App Store and Google Play submission discipline, staged rollouts, crash analytics, OTA update strategy, and App Store Optimization to turn launch into install velocity. We've shipped through every reviewer pattern; you skip the rejection cycle.
Amplitude or Mixpanel instrumentation, server-side event pipeline, A/B testing harness (Statsig, GrowthBook, or in-house), funnel and cohort reporting that ties to revenue. The data layer that makes every release a learning event.
Two-week sprint covering user research, competitive teardown, technical feasibility, and platform strategy (native vs cross-platform). You finish with a shippable scope, a realistic timeline, and an architecture decision record.
Information architecture, interaction design, and a clickable prototype tested with real users before a line of native code is written. Design system that scales with the app, not just the launch screens.
Two-week sprints, weekly demos, TestFlight and internal-testing tracks, staged App Store and Play Console rollouts. Performance budgets, crash-rate gates, and a real launch playbook — not a single ship-and-pray release.
Monthly release train, A/B testing program, store-rating monitoring, OS-version forward-compatibility work, and the dependency hygiene that keeps a 4.7★ app a 4.7★ app three years in.
A Japanese DTC brand needed a native shopping app to defend retention as paid acquisition costs climbed. We ran discovery with their loyal customer cohort, designed a tab-bar-led commerce experience tuned to LINE-style conversational flows, and shipped iOS and Android in parallel from a React Native + Expo codebase with native modules for AR try-on. Inside ten months the app had 380K monthly active users, accounted for 41% of company revenue, and held a 4.8★ rating across both stores.
"Deebo built our app the way we wished our agency had built our website. Eighteen months in, they're still iterating with us — it doesn't feel like an agency relationship, it feels like an engineering team."
— VP Product, Japanese DTC brand
Named iOS and Android leads on every project, with React Native and Flutter specialists where the platform decision warrants. No junior left alone in Xcode the night before submission.
Native vs cross-platform is decided in the discovery phase against your team, your performance budget, and your roadmap — not against the framework we happen to like this quarter.
Roughly 82% of the apps we ship remain on an active engineering retainer two years later. The economics are designed for ongoing operation, not for a new pitch every six months.
Thirty minutes, no pitch deck. We listen, ask the questions that matter, and tell you what we'd actually do — even if that means recommending you don't hire us.
