An account at Chase, another at Nubank — and nothing adds them up.
You never really know how much you have, because half is in reais and half in dollars.

September PTAX dollar rate: R$ 5.1575 · from Brazil's Central Bank
If you live here and still have money back home
You know this mess.
A card gets close to its limit and your score drops.
In the U.S., credit utilization weighs on your score — and you only notice when the statement closes.
The spreadsheet starts strong in January and dies in March.
Two currencies, a rate that changes every month, formulas that break. No one keeps it up.
How it works
Three steps, and the whole month shows up.
- STEP 1
Add accounts and cards
Chase, Bank of America, Nubank, Inter — each account in its own currency. Cards with their limit and due date.
- STEP 2
Enter what came in and went out
In dollars or reais, the way it happened. The app converts at the month's rate — the official PTAX, or one you type.
- STEP 3
See it all on one dashboard
What's left over, where the money went, which cards need attention and how your balance changes month by month.
Features
Built for life between two currencies.
Dollars and reais side by side
Every entry in the currency it happened in.
Each amount is converted once, at that month's rate, and then frozen — your history does not change when the dollar moves. The year summary is always in dollars, so every month is measured with the same ruler.
- Brazilian Central Bank PTAX rate suggested every month, for reais
- Use your own rate whenever you want
- Repeating expenses are marked “recurring”, and one tap corrects it
Credit cards and score
See your utilization before the statement closes.
Each card shows how much of its limit is in use — under 30% is what helps a U.S. credit score. Sort by due date, balance, limit or usage.
- Total debt and available credit added up
- Each card's due date
- Month-by-month history
Accounts in both countries
Combined balance in dollars or reais, and how your net worth moves through the year.
Income goals

Why it exists
“I ran my life between Brazil and the U.S. on a spreadsheet. REGRA Finance is that spreadsheet, without the work.”
Renata, founder of REGRA Finance
It had five tabs: expenses, income, investments, cards and a summary. Twelve columns a month, reais on one side and dollars on the other, and the exchange rate typed by hand to make it all add up.
It worked — until it became too much work. REGRA Finance keeps exactly that structure, does the math for you and shows what matters: what came in, what went out, what's left and what needs attention.

FAQ
What people usually ask.
Do I need a credit card to try it?
No. Create your account with an email and password and use everything during the free trial. Only afterwards, if you want to keep going, you pick a plan and pay with PayPal.
Does the app connect to my bank account?
No. You enter amounts and balances yourself; REGRA Finance never asks for your bank password or access to your accounts. Less risk, and you decide what goes in.
How does the exchange rate work?
For the Brazilian real, the app pulls the Central Bank PTAX selling rate every day and uses it for any month that has no rate yet. If you prefer another value — the one from your own exchange, for example — just type it. Each entry is converted once and frozen, so changing the rate never rewrites what is already there.
My money outside the U.S. is not in reais. Does it work?
Yes. You pick the second currency when you sign up — Mexican peso, euro, pound and many more. The automatic rate (PTAX) exists only for the Brazilian real; for other currencies you type each month's rate.
Can I use it only in dollars, or only in reais?
Yes. You choose the currency of each entry, and the month screens switch between the two currencies with one tap. If everything you have is in the U.S., using dollars only works fine.
Is my data safe?
Each account only sees its own data, the connection is always encrypted (https) and passwords are stored with one-way encryption — not even administrators can read them. Payment happens at PayPal: the app never sees your card number.
What if I cancel?
Cancel anytime under My account and keep using the app until the end of the period you paid for. Your data stays there; if you want everything erased, the delete-account option is on the same screen.
Does REGRA Finance give financial advice?
No. It is a tool to organize and see your money. Decisions about investments, taxes and credit are still yours — with professional help when needed.
Does it work on my phone?
Yes, with an icon on your home screen, like an app. On Android, Chrome offers to install it; on iPhone, it is Share → Add to Home Screen, in Safari. It is not an app-store app and it needs internet — the steps are in “Put it on your phone”.
Dollars, reais and credit cards — finally in one place.
