Runway
A private cash-flow forecast that shows how long my money lasts and what changes would stretch it.
Runway is a day-by-day cash forecast for the next twelve months. It projects my balance from recurring bills, subscriptions, paychecks and a monthly spending budget, then shows when the balance would first dip below zero.
Everything is adjustable: toggle a bill off to see what cutting it buys, change the budget by category, or compare different income scenarios. Edits save automatically, so it always opens where I left off.
The tool itself is private and needs my Google sign-in, since it runs on my real numbers.
