Android · iOS · Backend & web

Mobile apps that work properly at scale.

We build mobile apps end to end: Android and iOS, plus the backend and web around them. Fast, easy to release, and built to last from day one.

01 · Built to last

Most apps are built to launch. We build them to last.

Green Build Labs is built on 11 years of hands-on mobile engineering, including an app with millions of users. That's where you learn what goes wrong after launch, so we design it out from day one.

  • Launch time creeps up.Fast startup, designed in from the first build.
  • The release process becomes a weekly ordeal.Automated releases and testing from day one.
  • The app gets slow on the devices most of your users actually own.Built and tested for the devices your users actually own.

03 · How we work

We build it. Or we tell you how.

$ implement

We build it.

Delivered to an agreed scope.

A complete mobile solution from app to backend, with performance and release automation built in from day one.

$ consult

We tell you what to do.

We look at your plans, app or process and give you a clear plan.

For an existing app, that's a Diagnose: a short engagement on why it's slow, why releases hurt, and what would fix it. It ends with a written answer you could hand to your own team.
