Track every dollar the Kakeibo way. Sort spending into Needs, Wants, Culture and Unexpected, set goals, and finally see where your money really goes.
Katana is a budgeting app built on Kakeibo, the Japanese art of mindful money. Know what comes in, cut what doesn't count, and keep the rest.
Instead of endless categories, Katana sorts your spending into four simple pillars: Needs, Wants, Culture, and Unexpected. At a glance, you can see whether your money matches your intentions.
Log spending in seconds. A fast, focused entry screen keeps tracking effortless.
See where it goes. Clear monthly insights show your spending across the four pillars and how it changes over time.
Save on purpose. Set savings goals and watch them grow as you close each month.
Share a household. Budget together with the people you live with, so everyone contributes to the same plan.
Make it your own. Create custom categories that roll up to the pillars, and export your data whenever you want.
Katana is calm, private, and ad-free, with a monochrome design that stays out of your way.
Katana Premium unlocks household sharing, spending trends, custom categories, and data export. It's available as a monthly or annual subscription, or a one-time Lifetime purchase.
Save with intention.
