Process

From idea to live app in four steps

  1. 01

    Plan

    We agree on the screens and the data model before any code is written.

  2. 02

    Build in milestones

    You get a test build after each milestone and can try the app on your phone.

  3. 03

    Launch

    I publish the app on Google Play and deploy the backend and admin panel.

  4. 04

    Support

    After launch I fix bugs and add features as your users ask for them.
