KaBuddy: Budget & Kakeibo

KaBuddy - Your personal Kakeibo ledger

Take control of your money with intention.

KaBuddy is a modern personal finance app inspired by the Japanese Kakeibo (家計簿) method, developed by journalist Motoko Hani over 100 years ago. Instead of just tracking numbers, KaBuddy helps you build awareness, reflect on your habits, and develop a sustainable approach to saving.

A simple method with powerful impact

Each month, ask yourself:

1. How much income do I have?
2. How much do I want to save?
3. How much am I spending?
4. How can I improve?

KaBuddy guides you through this process-turning everyday spending into meaningful insight.

Understand where your money goes

All expenses are categorized into four intuitive groups:

1. Needs - essentials like rent, groceries, bills
2. Wants - non-essential purchases and treats
3. Culture - books, learning, experiences
4. Unexpected - irregular or surprise expenses

This structure helps you reflect - not just track.
