From requirements to release, in phases

You tell us the modules, features and phases. We turn them into a plan with a fixed quote, then ship it in working increments.

  1. Step 1: Requirements

    You share the modules, features, platforms and phases you need.

  2. Step 2: Architecture & estimate

    We propose the stack, a phase-by-phase plan and a fixed quote.

  3. Step 3: Build in phases

    You get working builds every week through TestFlight or internal testing, and a demo at the end of each phase.

  4. Step 4: Launch

    We handle App Store and Google Play submission, including review feedback.

  5. Step 5: Scale

    After launch we add analytics, performance work, new modules and automation.
