Household Financial Planning System
Manage household income, expenses, savings, investments, travel budgets, and goals.
The whole household's money in one place rather than two people guessing at each other's spreadsheets: income, bills, savings, investments, the travel fund and the goals they are all supposed to serve. It shows what is genuinely spare after everything committed has been counted.
What a v1 does5 features
- Every account and card from both partners in one view
- Bills and subscriptions detected and dated automatically
- Savings goals funded on a schedule rather than from what is left
- A spare-money figure that is honest about upcoming commitments
- A monthly summary both people can read without an argument

Why this audience
Behind family travel and family life is a household budget being managed by two people, usually badly and in two places. This audience is already thinking about money in family terms rather than personal ones. A system built for a household rather than an individual matches how they actually decide.

Fifty thousand paying users is the ceiling every one of these pages is drawn against, not a forecast. It opens at a thousand, the bottom of the range, so the first figures you see are the modest ones. What the cap buys is comparability: the same range on every app, and the percentage of the audience it takes as the number that moves.
