Mobile Apps

Apps people keepon the homescreen.

We design and build mobile apps for the long tail of devices people actually own. Native where it matters, React Native where it does not, App Store and Play Store paperwork done by us — and the first awkward week after launch handled by humans, not bots.

Capabilities

Four practices, one mobile team.

01

iOS development

SwiftSwiftUIXcode

Native iOS apps that feel like they were made by Apple. Fluid animations, proper haptics, and platform conventions that users expect.

  • Swift & SwiftUI
  • UIKit for complex layouts
  • Core Data & CloudKit
  • HealthKit & CoreLocation
  • ARKit & Vision
  • TestFlight & App Store submission
02

Android development

KotlinJetpack ComposeMaterial 3

Modern Android apps built with Kotlin and Jetpack Compose — Material 3 design, adaptive layouts, and the full Google ecosystem.

  • Kotlin & Jetpack Compose
  • Room & DataStore
  • Google Maps & Location
  • Firebase & Play Services
  • Adaptive layouts & foldables
  • Play Store submission & ASO
03

React Native cross-platform

ExpoNew ArchitectureOTA updates

One codebase for iOS and Android without sacrificing native feel. Over-the-air updates mean you ship fixes without App Store review.

  • Expo & bare workflow
  • React Navigation
  • Native modules & bridges
  • OTA updates via EAS
  • Offline-first with MMKV
  • Reanimated & Gesture Handler
04

App Store & growth

ASOSubscriptionsPush

Getting your app built is half the battle. We handle submission, App Store optimisation, and the revenue mechanics that make apps sustainable.

  • App Store & Play Store submission
  • App Store optimisation (ASO)
  • In-app purchases & subscriptions
  • Push notification infrastructure
  • A/B testing & store listing
  • RevenueCat integration

How we work

From idea to App Store.

01
UX discovery
We map mobile-first user journeys and platform conventions before touching code. iOS and Android users have different expectations — we design for both.
02
Prototype
Interactive, testable mockup for stakeholder sign-off. We validate flows with real users before committing to a native build.
03
Native build
Hardware integrations, permission flows, offline sync, and native animations — all the things that make a great mobile experience.
04
App Store ops
CI/CD via Fastlane and EAS, beta distribution via TestFlight and Play Store, and full submission support for the first release.
