Kaching - Money Log

Felix Andrian

About this app

Kaching — the private money log.

Kaching is a simple, honest way to track your money. No account, no ads, no cloud, no data collection — your finances live only on your device, and the app works completely offline.

Everything you need to log and understand your spending:

Multi-wallet by currency — keep your cash, bank, and e-wallet balances separate, each in its own currency (IDR, USD, and 170+ more).
Instant logging — a fast numeric keypad, in/out in one tap, notes and categories (Food, Rent, Transport, Salary, and more, localized to your language).
Transfers & adjustments — move money between wallets, including cross-currency transfers with a live exchange rate, and reconcile a wallet to its real balance.
Insights — see your net cash flow per period with a spending chart and category breakdown. Totals are always shown per currency — never mixed.
History with filters — search by wallet, direction, and category, with day-grouped lists.
CSV export — take your data with you any time.
Dark mode — light, dark, or follow the system.
Bilingual — English and Bahasa Indonesia.
Privacy is the product. Kaching requests no sensitive permissions and declares no internet permission on Android. Your ledger never leaves your phone. If you ever stop using the app, simply delete it — your data goes with you.

Kaching is free and has no paywall. Made for people who want to know where their money goes — without being the product.

What’s new

New in 1.5.1:
• Insights for a single wallet — open any wallet and tap Insight for its own numbers
• Cash wallets show a runway: how many days your balance lasts
• Savings goals show the pace you need and whether you are on track
• Credit cards show the statement cycle, limit used, and days to due • Hide balances with one tap — the eye on Home masks every balance, while transactions stay visible
