Overview

What is FinTrack?

Most budgeting apps are built for accountants. FinTrack was built for people who just want to know where their money is going and whether they're on track. AI-powered categorisation, real bank connections via Plaid, and a goal-tracking system that actually motivates — all in a privacy-first package.

The Problem

Budgeting apps are too complex or too dumb.

Budgeting apps are too complex or too dumb.

Either you're staring at a spreadsheet with 40 categories, or you're using an app that requires a PhD to interpret. FinTrack was designed to be the thing in the middle — smart enough to be useful, simple enough to use every day.

The result?

Teams keep patching the problem with more tools, more headcount, or more manual work — none of which scales. FinTrack was built to fix the root cause.
