Release & care

Signed builds, staged rollouts and ongoing updates.

Our process

Four clear stages, each delivering a tangible result.

  1. Discovery

    Define the problem, target users and non‑negotiable constraints.

  2. Architecture

    Sketch screens, data flow and permissions before code.

  3. Build

    Write Kotlin, Compose UI and tests; deliver incremental builds.

  4. Release & care

    Stage rollout on Play, monitor vitals and provide updates.
