How a transaction moves through Budgie
Five screens of the real app, in the order you actually meet them.
Add it in three taps
The keypad opens first. Type the amount, keep the account Budgie already picked, and save.
It files itself
The merchant and its category land on the entry before you finish typing, decided by a model running on your phone.
Your bank, with nobody in between
Monobank cards and jars arrive through your own token, straight into the database on your phone.
See where it actually goes
Spending by category and by tag, for any period, and every slice opens the transactions underneath it.
Works with the radio off
Everything above runs from a database on the device. Aeroplane mode changes nothing about what you can see or do.
What an offline expense tracker can do
Accounts, budgets, analytics and bank imports, all running from the same local database.
Offline-first expense tracker
No account, no cloud sync, no tracking. The database lives on your phone and the app never needs a connection to open, search or calculate anything.
Net worth tracker for mobile
Cash, bank, savings, crypto and debt in one number, converted daily.
Monobank sync with no aggregator
Your own token calls the bank API directly. No Plaid, no data broker.
Budget limits that match your payday
Set a monthly ceiling and per-category limits that reset when you get paid.
Spending analytics that actually help
Category and tag breakdowns for any period, each one drilling into its transactions.
Recurring payments calendar
Detected subscriptions laid out by date, so renewals stop surprising you.
All Budgie features
Voice entry, split transactions, tags, multi-currency, PDF and CSV imports and more.

Why offline-first and source-available matter
There is no server to phone home to
Every transaction, budget and chart is computed from a SQLite database on your phone. There is no account to create, so there is nothing to sign into, nothing to sync and nothing to leak. Turn the radio off and the app behaves exactly the same.
How offline-first expense tracking worksYou do not have to take our word for it
The application source is published under the O'SAASY license, so anyone can read the code that touches money, check that nothing is uploaded, and open an issue when it is not.

Quotes from anonymized beta tester feedback. Names and locations have been changed to protect privacy.
I was spending way more on "small purchases" without realizing it. Budgie showed me the truth in the first week. The breakdown by category was eye-opening.
I found recurring subscriptions I had completely forgotten about. Cancelled them straight away, and those small amounts really add up.
The privacy aspect sold me. My financial data stays on my phone. No company is mining my spending habits. That's how it should be.
