Truly multi-currency

Every account in its own currency. One household total, converted honestly, updated hourly.

Shared with your partner

Unlimited books, unlimited bookmates. Both of you log, both of you see, both of you decide.

Private by design

No bank connection required, ever. Manual entry stays first-class. Your data stays yours.

If you live across currencies,
every app is the wrong app

Your salary lands in USD on Wise. Your rent goes out in hryvnia from Monobank. Your savings sit in a euro account you opened in 2022. Your partner has their own version of the same picture. Every bank app shows one slice of it.

The workaround most of us settle into is a spreadsheet that worked for a quarter, then drifted out of date, then quietly broke. The other workaround is to just not look — which is fine until you need to make a decision together and neither of you knows what the real number is.

KungFuMoney is built for this. Every account in its own currency. One household total, in whichever currency you want it. Both of you on the same page, every time you open it.

How it works

Four steps. About three minutes from sign-up to first useful number.

01

Create a book

A book is a shared space for a household's money. Start with one — most people only ever need one. You can have as many as you want, for as many separate financial lives as you keep.

02

Add your accounts

Each account has its own currency — a Monobank UAH card, a Wise USD account, a euro deposit, a cash envelope. Add what you actually use; ignore the rest. Manual entry stays first-class. No bank login required.
Account creation form
03

Invite your partner

Send one join link. When they join, both of you can log transactions, see balances, and assess spending. Books are shared end-to-end, not "one of us owns it, the other watches."

04

See your household total

One number, in your currency of choice, updated every time either of you logs anything. The same number you both see when you open the app. The conversation gets easier when you start from the same picture.

Why we built this

Vitalii Mashchenko, founder, KungFuMoney

My wife and I tried every budgeting app on the market. None of them understood that we earn in three currencies, spend in two, and save in a fourth. We ended up with a spreadsheet that worked for a while and then didn't. So I built the app I wanted us to have — for couples who live across currencies, in Kyiv, Warsaw, Berlin, or anywhere else.

Questions people ask before signing up

01

Do I have to connect my bank account?

No. KungFuMoney does not require a bank connection — and we don't plan to require one. You add transactions manually, paste them from a CSV, or scan a receipt when we ship that feature later this year. The trade-off is honest: you do a little more typing, and in exchange your financial data never leaves your hands or ours.
02

How does the multi-currency part actually work?

Each account belongs to exactly one currency — a hryvnia card, a dollar account, a euro deposit. Transactions stay in the account's currency, always. Your household total is shown in the currency of your choice, converted at the current rate. Every transaction is visible in both the account currency and your chosen currency, so the conversion is never hidden. Rates update hourly.
03

Can my partner use my account?

Yes. Open the account's settings and turn on the "Joint account" option. Once it's on, every bookmate in that book can add transactions to the account and edit existing ones.
04

Should each member of my household pay for a subscription?

No. KungFuMoney is built for shared household use. You create a book — a shared financial space — invite your partner or anyone else in the household, and everyone in the book can add transactions, see balances, and edit anything. One subscription covers the whole book: as long as at least one member of the book has an active subscription, everyone in the book has full access. You don't pay per person.
05

What happens when my trial ends?

You decide whether to subscribe. If you do, everything continues without a blip. If you don't, your account stays — you keep read-only access to all your data, can export everything as CSV anytime, and can resume full access by subscribing later. Nothing is deleted, and there is no countdown on your data.
06

Is my financial data private?

Yes. We don't sell data, we don't run third-party analytics on your transactions, and we don't require a bank login. Your data lives on servers in Beauharnois, Canada — a region the EU recognizes as offering equivalent data protection. You can export everything as a CSV anytime, and you can delete your account from inside the app.
07

What languages does it support?

English, Ukrainian, and Russian at launch. Polish and Czech are next, with the rest of Central Europe following in 2026 and 2027. The product is the same in every language — only the words change.
08

Is there a free plan?

Not a feature-limited free tier, no. The 30-day free trial is the way in — no credit card to start, full access from day one. After the trial, KungFuMoney is $3.99/month or $39.90/year. If you choose not to subscribe, your account stays in read-only mode and your data stays yours.
09

Why KungFuMoney?

Because handling money across currencies — across borders, across a relationship, across a decade — is a practice. It's not a one-time setup, and it's not a trick. It's something you get better at. The name is a small reminder of that.
