Services

What we build for clients.

We take on contract work across mobile, web and backend — the same stack we use for our own products.

01

Cross-platform mobile apps

Store listings, policy compliance and ad mediation — the work between a finished build and a live listing.

  • ASO listings written for the store you are targeting
  • Policy compliance review before you submit
  • Ad mediation setup with AdMob and LevelPlay
  • Publishing to Play, Galaxy Store and AppGallery

How we build

Spec first, then ship, then read the numbers.

  1. 01

    Spec

    We write the PRD first. Scope, screens, data model and edge cases are settled before any code is written.

  2. 02

    Build

    AI-assisted engineering against that spec, reviewed by hand. The spec stays the source of truth.

  3. 03

    Ship

    Multi-store publishing — Google Play, Galaxy Store and AppGallery — with the policy and listing work done.

  4. 04

    Iterate

    Then we read what the numbers say, and change the product rather than the pitch.
