A premium, commercial-grade family expense tracker & financial insights tool — built end-to-end as a personal & partner project.
Joint accounts, dynamic categories, budget planning, a bill calendar, monthly archives & an AI advisor — all under one private cloud-synced login.
Most budget apps are built for one person. Real households share rent, share groceries, split insurance — and need a single source of truth that both partners trust.
Family Wallet started as a spreadsheet between two people — rent, bills, the loan, the shopping — and grew into a full personal-finance platform I now run for our household.
I designed it as a premium, commercial-grade product from day one — secure individual + family account sync, dynamic categories with icons, professional-grade charts, an interactive bill calendar, and an AI layer for smart expense processing.
The goal: replace four tools we kept reaching for — a spreadsheet, a banking app, a calendar & a notes file — with one focused view of the month.
Built solo, end-to-end. React frontend, Node & PostgreSQL backend, JWT auth, deployed cloud-synced. Now on version 2.1 and still our daily driver.
Family Wallet treats household money the way Linear treats a sprint: opinionated, fast, and obsessively visual. Dark-mode UI, emerald accents, every screen designed before it was built.
Per-user accounts with secure family sync — invite your partner with a six-character code, share categories & goals but keep individual income visible.
Dashboard, Categories, Record Daily, History, Planning, Savings, Reports, Calendar, Month History & Profile — all under one nav bar.
A walkthrough of the eight surfaces you'd actually use in a month — the auth gate, the live dashboard, the bill calendar, the savings planner & everything in between.
A reasoning layer that classifies transactions, spots anomalies & suggests budget tweaks at the end of every month — built on top of Claude.
Every recurring bill — rent, insurance, optus, NIB, loans — laid out on a month grid with paid/unpaid state and an upcoming-bills sidebar.
Each module earned its own tab through actual use — the things we kept opening, not the things that sound clever in a feature list.
Balance, required funds, projected surplus & per-partner income at a glance.
Custom categories with unique emoji icons & per-category budget caps.
A frictionless one-tap entry screen optimised for thumb-speed input.
List + analytics views — monthly income, total spend, savings rate.
Set a shared financial goal & allocate the monthly surplus toward it.
Bring-forward, net savable & lifetime savings — finalise once per month.
Pro-grade charts & monthly trends powered by Recharts.
Visual month grid & upcoming bill sidebar — never miss rent again.
Lock each month, archive the totals, run reset for the next cycle.
The same Family Wallet, ported to iOS and Android. Cloud-synced with the web — record a coffee on the train, log rent at the gate, see the same number from both sides of the bed.
Create an account, generate a six-character invite, and your partner joins your household. Categories, goals & bills sync both ways instantly.
One-tap entry for daily spend. The AI advisor reads the merchant string and pre-fills the right category — coffee, groceries, fuel — in under a second.
Set rent, insurance, phone & loans as recurring with monthly or fortnightly cadence. Each one lands on the calendar, surfaces on the dashboard the day it's due, and clears with one tap.
Live balance — required funds — bring-forward = net savable. Drag-prioritise savings goals & the planner allocates the surplus in priority order, every payday.
On the 28th, the app prompts a one-tap close — locks the month, archives the totals into Month History, rolls leftover savings to next month's bring-forward, and resets the next cycle clean.
Web on the laptop at home, native iOS or Android on the train, the same single source of truth. PostgreSQL on the backend, JWT auth, cloud-synced.
I wanted one URL where my partner and I could open the month and agree on the number — Family Wallet is that URL.Pasan W. · Solo builder & daily user
