My Money Ledger
A personal finance app I’m building to help people understand where their money goes and see their spending more clearly.
Connect bank accounts through Plaid into a local ledger on iPhone and Mac, then ask questions about your finances.
Engineering behind the app
I built the app, data workflows, and assistant. Qwen3 on device (MLX on Mac, a 4-bit quantized model on iPhone), Apple’s foundation model, and Claude use the same eight read-only tools; tested code calculates financial figures, and a grounding check verifies that response numbers came from tool results.
That keeps calculations in code while models explain the results.
