What Async Digital delivers

Native apps

For iPhone, iPad, and Mac, written in Swift and SwiftUI.

Connectors for AI assistants

Connectors that bring an organisation’s own information into AI assistants such as ChatGPT and Claude, built as MCP apps, in English and Welsh. A working demo is available on request.

Bilingual from the first build

The app remembers each user’s choice of language and handles Welsh plural forms. The client’s translators supply the Welsh text and the app is built to hold it.

On-device search and transcription

For data that shouldn’t leave the device.

Release and support

Release to the App Store, with support after launch on terms agreed in the contract.

How the work is checked

The code comes with automated tests and documentation, and goes through three stages before anything ships.

Stage 1
Automated tests

The work goes through automated tests before it is reviewed.
Stage 2
Automated review

Checks enforce the project’s rules before sign-off.
Stage 3
Director’s review

Rob reviews the results and signs off before anything ships.

The checks are public

Seen to Fail is one of the company’s own tools, listed under Shipped work below. Its source code and its record of how each of its checks was tested are both open, so a buyer can see what the company’s own tool checks and how each check was tested.
