App Development

Apps that feel at home on every phone.

We build native iOS and Android apps in Swift and Kotlin, and cross-platform apps in React Native when one codebase makes more sense. Fast, secure and ready for the store.

Why it matters

An app lives in someone's pocket, next to the best software in the world. So we build it natively, test it on real phones, and sweat the details people only notice when they're missing.

What we build

Everything a serious app needs.

  • Native iOS and Android

    Swift and SwiftUI on iPhone, Kotlin and Jetpack Compose on Android, so every screen moves the way the platform does.

  • Cross-platform when it fits

    React Native and Expo for apps that should ship to both stores from one codebase, without feeling like a web page.

  • AI on the device

    ID cards, barcodes and text read by the phone's camera, on the phone, so it works fast and the data stays put.

  • Security built in

    Encrypted storage, certificate pinning, OTP sign-in and device checks, the way a finance app must be built.

  • In your customers' language

    Apps that switch between languages, including Sinhala, Tamil and English, with type that reads well in each.

  • Notifications that help

    Reminders, alerts and updates sent at the right moment, not a stream of noise people learn to ignore.

How we work

One team, from first conversation to launch.

  1. 01

    Discover

    We sit with the people who'll use it and map the work before we design anything.

  2. 02

    Design

    Clickable prototypes on a real phone, so you feel the app before it's built.

  3. 03

    Build

    Native code and a tested backend, delivered in working releases every couple of weeks.

  4. 04

    Launch

    Store listings, reviews and release, handled for both App Store and Google Play.

  5. 05

    Run

    Monitoring, fixes and new features after launch, from the team that built it.
