Logging

Tap an amount, pick a category. Done.

Your usual categories come first, and it remembers which card you paid with last time. You can also just say "lunch, twelve dollars" — it is understood on your iPhone, not in the cloud.

Overview

See where it went.

Net worth, what you have spent this month and what is left in your budget, all on one page. One bar per day, so the expensive days stand out.

Calendar

Your month, shaded by spending.

The darker the day, the more you spent. Debits, card payments and paydays are marked too, so the end of the month holds no surprises.

Multi-currency

Abroad? Log it as you paid it.

Record the amount in the currency you paid, converted at that day’s rate. When your bank posts the charge, match it to what you were actually billed. Estimates and actual amounts stay separate.

  • Hold several currencies in one account
  • Daily rates are saved, so old entries never shift
  • No rate available? It says "unknown" instead of guessing

Accounts & cards

Card statements, reconciled for you.

Closing dates, due dates and shared credit limits are worked out, and payments reconcile automatically. Add bank accounts, e-wallets, crypto and stocks — your net worth adds itself up.

Reports

Seven reports. A clearer view of your money.

Cash flow, top categories, monthly net worth, period comparisons, subscription costs and more. Switch between months and years, and tap through to the details.

Shared accounts

Share the household books.

Share an account with family, flatmates or a partner — up to 30 people. Everyone logs from their own phone, and you can see who added what. Choose who can view, log or manage.

And also

Subscriptions & bills

Recurring charges log themselves. Price changes never rewrite the past.

Splits & IOUs

See who owes whom, and settle up in one tap.

Budgets & reports

Category budgets, monthly reports and a yearly recap.

E-invoices

Scan or import Taiwan e-invoices and match them to entries.

Investments

Stocks, ETFs and precious metals, with gains based on your cost.

Widgets & Siri

Check balances from your Home Screen, or log by asking Siri.

Security & privacy

Private by default. Secure by design.

Fully usable without an account

If you don’t sign in, everything stays on your iPhone and is never uploaded.

Encrypted in transit and at rest

Data always travels over TLS, and it is stored encrypted in the cloud.

Accounts kept strictly apart

Each account can only reach its own data, enforced by access rules in the database itself.

No passwords

You sign in with Apple, so we never see your Apple Account password. Sign-in tokens stay in your device’s Keychain.

No ads. No data sales.

There are no ads in the app, and no third-party analytics or tracking.

Take it with you, or delete it

Export CSV or a full backup at any time. Delete your account and your cloud data is gone for good.
