Buying together, split fairly

Two incomes rarely split a mortgage exactly down the middle, but most tools assume they do. If one of you earns more, or wants to put in more, the numbers should say so. A slider, not a default, and it carries through every shared bill, not just the mortgage.

• Shared bills, your waySplit evenly, or lock a bill to whoever's actually paying it: council tax, energy, whatever fits.
• See who owes whoWhen there's no joint account, a settle-up suggestion works out the one transfer needed to keep things even.
• Tracked properlyOne mortgage, two people: balance, payoff date, and each person's share, all in one place.
