Kakeibo: Budget Planner

Save first. Live on the rest.

Kakeibo is a budget planner and expense tracker built on kakeibo, the Japanese method of mindful spending. Set your savings aside at the start of the month, write down what you spend, and look back at the end of it. No bank linking, no sign-up, and your expense log works offline.

How the kakeibo method works

Kakeibo (家計簿, "household ledger", also written kakebo) was introduced in 1904 by the Japanese journalist Hani Motoko. The idea is simple: when you record each expense yourself, you see where your money really goes. That is the heart of mindful spending, and it makes impulse buys easier to skip.

1. Enter your monthly income
2. Choose your savings goal first
3. Split the rest across four pillars
4. Log each expense as it happens
5. Reflect at the end of the month

Four pillars instead of fifty categories:
• Needs: rent, groceries, bills, transport
• Wants: eating out, shopping, treats
• Culture: books, courses, music, experiences
• Unexpected: repairs, doctor visits, gifts, surprises

Free features
• Fast expense entry with a pillar suggestion as you type
• Monthly budget that shows what is left to spend
• A savings goal with progress and an optional target date
• Spending calendar with a heat map, no-spend days and streaks
• Monthly reflection with the four classic kakeibo questions, plus a journal
• Edit any entry: amount, pillar, date or note
• Home screen widgets for your remaining budget and one-tap quick add
• A gentle daily reminder to log your spending
• CSV export, dark mode and every currency

Use Kakeibo as a simple expense tracker, a monthly budget planner, a money diary for a no-spend challenge, or a way to save money for something that matters. You stay in control, without handing your bank details to anyone.
