Spacetime Ledger

Your balance ten years out, on today's screen.

A household ledger that joins your past records and your plans into one line. See your balance ten years from now, or the day your loan is paid off, on the same screen you use today. You know what it takes to keep living the way you do.

Timeline with three lines — assets, liabilities, and cash — from ten years back to ten years ahead. Assets and liabilities spread apart the year a home is bought, and liabilities climb back toward zero as the loan is repaid

Balances ahead

See ten years ahead the way you see today

Move the date at the top of the screen, and Home — assets, liabilities, net worth — and the Timeline all switch to that moment. Today is treated as just another day, so looking back ten years and looking ahead to the day your loan is paid off work the same way. Money on a fixed cycle, like rent or salary, is recorded once and laid out ahead (a repeat).

Home with the date at the top moved to 10/28/2036, showing assets, liabilities and net worth ten years ahead, plus that month's income, spending and net income

Big purchases

Homes, appliances and annual bills, spread over the months you use them

Things you use for years, like a home, a car or appliances, and annual bills like insurance and taxes, can be spread across months (a split). Spending doesn't spike in the month you pay, and what hasn't been spread yet stays in your assets. If you sell or let go of something early, you can end it on that day.

Record

Just pick a source and a destination

When money moves, choose where it came from and where it went (source → destination), then enter the amount. From a button on Home, just drag a source chip onto a destination chip. The buttons can be set to the pairs you use most.
