Everything a household needs, kept simple
Built first and foremost to be something you can keep using every day.
One book for the family
Invite your family with a code. Whoever records something, everyone sees it right away.
Record in 10 seconds
Type the amount on the keypad and pick a category. Your usual shops are one tap away.
Budgets and alerts
Set a monthly budget and budgets per category. Colors and icons warn you before you overspend.
Clear reports
Spending by category, by day and by member, plus a 12-month trend — as charts or tables.
Settle up, too
Shared and personal expenses with split rules work out who owes whom. Households that don't need it can turn it off.
In four languages
Japanese, Chinese, Vietnamese and English. Everyone uses the same books in their own language.
Keypad and quick inputs for fast entry
Enter the amount, pick a category, tap the shop. Save your usual shops per category, and attach receipt photos.
Notice overspending early
See how much of each budget is used and the forecast for the month. You can also assign who looks after each budget.
Settle up automatically
Shared expenses are split by your rules and turned into a plan with the fewest transfers. Once everyone confirms, the month is closed.
See where the money goes
A category donut, daily spending and a comparison with last month — or switch everything to tables.

Frequently asked questions
Does it cost anything?
It's free to use, with no ads.
Is there an Android app?
We offer an iPhone app and a web app. On Android, please use the web app in your phone's browser.
Can it connect to my bank or credit card?
No. That way you never hand over your logins — instead, the keypad and quick inputs make recording fast.
How many people can use it together?
There is no limit. Couples, parents and children, or anyone living together can use it.
Do we have to use settling up?
No. Turn off "Splitting and settlements" in the household settings and everything is simply household income and spending.
How do I delete my data?
Delete your account from "My page" in the app or "Account settings" on the web. If you are the last member of your household, all of the household's data is deleted too.
