Moneta: iOS Personal Finance

Most personal-finance apps track spending loosely. Moneta applies the double-entry discipline from accounting software to personal money.

It’s an independent project that I design and build alone.

• Money must never drift through floating-point rounding.
• Every movement of money must balance, across several accounts.
• Personal financial data must stay behind a lock.

• Double-entry ledger records stored as whole paise, never floating-point values.
• Support for multiple accounts.
• An app-level biometric and passcode lock.
• A native SwiftUI interface backed by Firebase.

Double entry is more work than a simple list of expenses, but it means every balance can be explained and checked.

In internal testing.
