History & About

Twenty years to a
$0 month.

A budget built from two decades of spreadsheets, envelope systems, paper ledgers, and hard conversations about money.

Every couple has a money story. Ours started with two completely different philosophies living under the same roof. I was a spreadsheet person — credit cards for everything, Quicken for tracking, paid in full every month. My partner was a cash and checkbook person — paper ledger, never carried a balance, knew to the cent what was in the account.

Neither of us was wrong. But we weren't speaking the same financial language, and that creates friction. The spreadsheets I built were too complex for her to use independently. The paper system she kept didn't capture the bigger picture I needed to see. We tried everything.

"After countless iterations of spreadsheets and budget envelope systems, we have finally found something that has been working well for 2 years."

— The moment this app was born

The breakthrough came when we stopped trying to make one person adopt the other's system, and instead asked: what does each of us actually need to see? The answer was the core philosophy of this app.

Budget for needs. Fund wants from savings. Close the month, distribute the surplus, start fresh. Simple enough to check in 5 minutes a day. Powerful enough to handle irregular income, variable expenses, and two people with different financial instincts.

This app is our personal system, opened up to anyone who might benefit from it. It is free to use, ad-free, and the financial data you enter never leaves your device in readable form. This isn't a product designed to sell you something — it's a tool we actually use every single day.

How we got here

Early 2000s

The Quicken era

Tracking everything in desktop software. Precise, but not shareable. Partner kept a parallel paper system. Two books, one household.

Mid 2000s

The spreadsheet phase

First attempt at a shared system. Too many tabs. Too many formulas. "I'll just ask you what the number is" became the default.

2010s

The envelope experiments

Physical envelopes, then digital equivalents. Getting closer. The envelope concept was right, but the tooling was always off.

2020s

The breakthrough

Settled on the needs-vs-wants philosophy. Built a prototype. Both of us actually used it. That had never happened before.

2024–2025

Two years and counting

Running our household finances on this system for over two years. Rebuilt as a proper web app. Ready to share with the world.

The two people who built this

Designed for both kinds of people.

The Numbers Person
Credit cards · Spreadsheets · Quicken

Uses credit cards for everything for the rewards and tracking. Wants to see totals, trends, and year-over-year comparisons. Checks the dashboard compulsively. Loves that every dollar is accounted for.

The Paper Person
Cash · Checkbook · Pen and paper

Never carried a credit card balance. Kept a physical ledger. Needs the system to be intuitive without reading a manual. Cares about the big picture: are we on track this month, yes or no?

If your household has one of each — or even if you're somewhere in between — this app was designed for exactly that tension. The daily screen (Surplus) is simple and action-oriented. The reports and history are there for whoever wants to go deeper.

A note on privacy

Your financial data is deeply personal. We encrypt everything on your device before it ever reaches the server. The encryption key is stored locally — not in our database, not accessible to us. If the server were ever compromised, your data would be unreadable to an attacker.

This also means: please back up your data. If you lose your device and your encryption key, we cannot recover it. The export function is your safety net. Use it regularly and store the backup somewhere secure.

The app has no ads and we have no interest in your spending data. The core app is free to use on a single device. Syncing and collaboration are available as an optional paid plan.
