Save first. Live on the rest. Kakeibo is the Japanese art of mindful spending, created in 1904 by journalist Hani Motoko. Unlike modern budget apps that sync your bank and automate everything, Kakeibo asks you to slow down, write it down, and reflect. WHY KAKEIBO WORKS The secret is friction. When you manually record each expense, you build awareness. When you ask yourself "Do I truly need this?" before every purchase, impulse spending drops. The Kakeibo method is designed to help you spend more intentionally and build a steadier saving habit. THE FOUR PILLARS Every expense falls into one of four categories: - Needs (necessities you cannot avoid) - Wants (things you enjoy but can live without) - Culture (education, books, experiences) - Unexpected (repairs, medical, surprises) This simplicity is intentional. No 47 sub-categories. No decision fatigue. Just four honest buckets that reveal where your money really goes. HOW IT WORKS 1. Set your monthly income 2. Decide your savings goal FIRST 3. Budget what remains across the four pillars 4. Record every expense mindfully 5. Reflect at month's end: What went well? What can improve? WHAT MAKES THIS APP DIFFERENT - No bank linking, no cloud servers — your data stays on YOUR device - Designed for the Kakeibo philosophy, not generic expense tracking - Monthly reflection prompts based on the original Japanese method - Beautiful, minimal interface inspired by Japanese aesthetics - Works completely offline - Widget support to keep your budget visible KAKEIBO PRO Unlock personal coaching insights, spending trends, recurring-expense detection, the large Home Screen widget, and CSV import with Kakeibo Pro. - Monthly and yearly plans.

Whether you follow Dave Ramsey's envelope method, practice zero-based budgeting, or simply want to spend more intentionally — Kakeibo gives you the mindful framework to save first and live better. 「千里の道も一歩から」 A journey of a thousand miles begins with a single step.
