How I work

A clear path from first call to launch

  1. 01

    Discover

    We agree on goals, users, scope and what success looks like before any code is written.

  2. 02

    Design

    Flows, screens and the technical plan: data, APIs and how the app will scale.

  3. 03

    Build

    Short iterations with test builds on your phone every week, so you see progress early.

  4. 04

    Ship & support

    App Store and Google Play release, monitoring, and updates after launch.
