Applications and Digital Products.

We now build what we recommend: native iOS and macOS applications, web front ends, service integrations and data products — delivered by the people who wrote the roadmap.

What we build

Native Apple applications

Swift and SwiftUI applications for macOS, iPadOS and iOS — local-first, private by design, and at home on the platform. Our own HelloNotes and FinvestLens are built this way.

Web front ends

JavaScript and TypeScript front ends, including apps embedded in enterprise portals such as ServiceNow — delivered as clean, testable components.

Enterprise integrations

Authentication via Azure AD / Entra ID, data through Microsoft Graph, and SAP OData services connected via SAP Cloud Platform to on-premise systems.

Data products

Dashboards, machine-learning-assisted workflows and analytics applications on AWS — turning the models we recommend into tools people use daily.

Proof, not promises

Hello Tham
FinvestLens 1.0 — double-entry accounting for Apple platforms
A native accounting application for macOS, iPadOS and iOS, built on the rigour of the GnuCash engine: local SQLite documents, bank imports across six formats, on-device intelligence and annual-report-grade reporting. Verified against a real 46,000-transaction book to the cent, and released as free software under GPL v3.

Hello Tham
HelloNotes 1.0 — a local-first Markdown knowledge base
A native Mac knowledge base whose database is an ordinary folder of Markdown files: live styled editing on TextKit 2, wiki-links and backlinks, a native graph view, Git history, cloud-folder support and on-device intelligence. Signed, notarised and free.

Both are built with the same practices we bring to client work, and both are yours to download and inspect. See all our apps, or our client engagements — including native iOS, ServiceNow and chatbot proofs of concept for government — in Achievements.

Have an app in mind?

Start with a proof of concept — we scope small, deliver early and refine with the people who will use it.
