What is OneTruth Money?

The short answer

OneTruth Money is an iOS personal-finance app for people who share money. It tracks your bills, income, and budgets, and turns them into one number — Safe to Spend — that lives on every Member’s lock screen and updates the moment anything changes. It just works. No setup.

01Safe to Spend

Why this number holds.

The math is deliberately boring: your real available cash, minus upcoming bills, minus Keep in Account, minus pending charges and Money Requests. What remains is what you can spend right now without breaking anything.

It recomputes as life does — a bill gets paid, a paycheck lands — and every Member sees the same figure. Not a per-person version of the truth. One number.

02The same number, two phones

Mark a bill paid on one. It’s already true on the other.

No screenshot, no “did you see it?”, nothing to open. The number you both trust settles on every phone at once.

Live demo: two iPhones show the same Safe to Spend number. When the water bill is marked paid on one, the number updates on both — the same figure on every phone.

04Members

Nobody has to be the bad guy.

Everyone you invite joins as a Member — free and unlimited, paid for by one subscription. Each Member has their own login and their own account; what they share is the number, not their passwords.

The activity feed records facts — the water bill is paid, the paycheck arrived — never who to blame. The ledger does the talking, so no one has to.

Activity

  • Water bill marked paid−$55.00

  • Paycheck arrived+$2,060.00

Every Member sees the same feed, the moment it changes.

05Workspaces

One shared-money engine, many rooms.

A household, a rent split, a trip, a side gig — each keeps its own number and its own people. The college fund and the payroll never meet.
