SparkyToolkit

// the problem

Australian electricians juggle calculations, standards references, test records, and compliance paperwork every day on site. Most reach for generic calculator apps, dog-eared copies of AS/NZS 3000, or spreadsheets cobbled together over years. There was no single, purpose-built tool that brought everything together in a way that works on a construction site.

// the solution

SparkyToolkit is a professional iOS field companion built specifically for Australian electricians. It combines 13 offline calculators, a quick reference to the AS/NZS 3000 wiring rules, digital test records with PDF and Excel export, and photo-based site plan markup, all in one app that works without signal.

The calculator engine is shared with ElecCalc.au, so both platforms stay in sync with the latest AS/NZS 3008 standards. The app is free to download, with a Cobber Pro upgrade at $7.99.

// architecture

The frontend is built with React Native and TypeScript, deployed as a single codebase to iOS, with a JWT-authenticated REST API behind it.

Sparky AI, an assistant trained on Australian electrical standards, is in development and listed as coming soon on the App Store. It uses a keyword-based RAG search over structured PDFs, which proved more cost-effective and accurate than vector embeddings for dense technical documents.
