Product overview

Simple enough to start, clear enough to keep using.

Instead of turning money management into a complicated accounting sheet, Expense Notebook focuses on your three core needs: speed, privacy and reliable figures.

FAST 30 seconds a day to take control of your finances

Remove the friction of tracking expenses with a workflow optimized for speed.

Instant entry: Add records from the Android home-screen widget, or use the floating menu to create and edit transactions with ease.
Payments & shared expenses: Keep track of amounts paid on behalf of friends and create or share VietQR payment codes in moments.
Make it your own: Choose a layout and color tone, customize the app icon and let the app fit your habits. Gentle reminders help logging become natural, without pressure.

SAFE Full control of your data stays with you

Personal spending data is sensitive, so the app is designed to respect and protect it.

Proactive protection: Manual backups are carefully encrypted, and your data is not silently synced to third-party servers without your permission.
Complete transparency: You decide when to restore, share or delete your data.
Independent storage: Export your data to an Excel file using filters, so you can keep and manage it on your own device.

TRUSTWORTHY A clear, accurate picture of your spending

Every figure reflects your actual activity, so you always know where your money is going.

Clear visual reports: See your situation at a glance with the 7-day chart, monthly overview and Top 5 spending list. Detailed filters make it easy to look back through up to 12 months of transactions.
Smart multi-currency handling: Supports VND and additional currencies. Foreign-currency transactions are fixed using Vietcombank's selling rate at the time of entry, preventing later exchange-rate movements from distorting your balance.
Separate every money source: Keep categories distinct and separate personal wallets, bank accounts and credit cards for accurate reconciliation down to the last đồng.
