Mobile App Development

Built for day 30, not for launch day.
Start a projectHow we measure it

We design, build and ship iOS and Android apps: native Swift and Kotlin when the product depends on the hardware, React Native or Flutter when one codebase gets you to market sooner. Store submission, the tracking plan, crash reporting and a 90-day retention plan are part of the build, not a later phase.

Most apps are opened once and deleted inside 3 days. That is settled in the first session, so we design onboarding, the empty states and the first useful moment before anyone touches the settings screen.
Native when the product leans on the device, such as camera, AR or low-latency audio. Cross-platform when it does not, which shares 80 to 85% of the code and cuts build cost by up to 40%. We put that call in writing before the build, not after you have paid for the wrong one.

What you get

Deliverables, specifically.

8 things you can point at. Scope is agreed in writing before the first invoice.

  • Discovery and MVP scope, with a clickable prototype tested on 5 to 8 people who do not work for you
  • Native iOS in Swift and SwiftUI, native Android in Kotlin and Jetpack Compose
  • Cross-platform builds in React Native and Expo, Flutter, or Kotlin Multiplatform where shared logic pays for itself
  • Backend and APIs, real-time sync and offline-first data, so the app still works underground
  • Auth, subscriptions and payments through RevenueCat, Stripe or in-app purchase, plus push and in-app messaging
  • App Store and Play submission, privacy manifests, ASO and store-listing tests
  • A tracking plan agreed before the first sprint, wired to product analytics, crash reporting and CI/CD
  • A 90-day retention plan: the cohorts to watch, the experiments to run, and who owns each one

How it runs

3 steps. Then it compounds.

Our method, narrowed to this service. Every step ends with a document, a build or a number you can check.

  1. 01

    Scope and prototype

    A discovery sprint, the technical architecture, and a prototype put in front of 5 to 8 real users. You get a written scope, a timeline and a quote within 2 weeks of kickoff.

  2. 02

    Build in sprints

    Two-week sprints, a TestFlight and internal-track build at the end of each one, and the analytics events written into the tickets rather than added afterwards.

  3. 03

    Launch and retain

    Store submission, ASO, a soft launch in one market, then retention dashboards and a 90-day run of experiments with owners and dates against each.

Questions

Asked often.

  • Cross-platform shares 80 to 85% of the code and cuts build cost by up to 40% against two native apps. Go native when the product leans on the camera, AR or low-latency audio, or when you need new platform features the day they ship. Kotlin Multiplatform is our pick when you want native interfaces with shared business logic.
