# Web and mobile development

> For established companies that need one product on the web, iOS and Android. We build all three on a shared design system and a single back end, so they behave alike and change together.

Established companies often end up with a website, an iOS app and an Android app built at different times by different teams. Features reach one platform long before the others, the same data lives in three places, and every change costs three times over. We build or rebuild the product as one: a shared design system, one back end and API serving every client, and web and mobile apps released together. Your customers get the same product wherever they meet it, and your team has one system to run.

## What you get

- **Parity across platforms**: Features released on the web, iOS and Android together instead of one platform at a time.
- **One back end and API**: A single source of data and business rules that every app reads from and writes to.
- **A shared design system**: Components and tokens used by the web and mobile apps alike, so the brand and the behaviour stay consistent.
- **Coordinated releases**: A release process that ships web and store updates on the same schedule, with testing on each platform.
- **Documentation your team can use**: API and system documentation written for the people who will run and extend the product.

## How it works

1. **Audit what exists**: We review your current site, apps and back end, and decide what to keep, merge or replace.
2. **Design the shared layer**: We define the data model, the API and the design system that every platform will use.
3. **Build platform by platform**: We build the back end first, then the web and mobile apps on top of it.
4. **Release together**: We ship to the web and both stores on one schedule, and move users over without breaking their accounts.
