For You

Built for people managing
a personal monthly allowance.

No need to "force yourself to save". Yarikuri is simple — yet it quietly changes how you handle money.

Features

Six things you can do with Yarikuri

Because it's a small app, every feature is designed to be effortless and easy to stick with.

💰

Today's budget at a glance

Based on your monthly budget and current spending, Yarikuri shows how much you can spend today and the remaining monthly balance.

✏️

Log expenses in three taps

Amount, category, memo — done. Six fixed categories (Food, Daily Goods, Transit, Hobbies, Social, Other) keep things friction-free.

🎯

Goals & total savings pool

Track multiple goals like "Travel fund — ¥50,000". Month-end leftovers are auto-deposited into your total savings pool.

💾

Backup & restore

All data stored locally. Export and import as JSON to migrate between devices.

🎨

12 languages, 8 themes

Supports 12 languages. Unlock six decorative themes for 24 hours with a rewarded ad. No purchases, no subscriptions.

🔒

Your data stays on your device

All your budget and spending data is kept on your own device — never on our servers. No account sign-up required.

What's Different

Not a household-budget app —
it's for your personal allowance.

There are plenty of household-budget apps. But almost none are built for the person who just needs to manage a personal allowance day by day.
Yarikuri makes "today's spending" the star.

Savings Example

A ¥30,000 monthly allowance
can still build real savings.

"Just save more" rarely works.
Yarikuri only shows you "today's budget" — and money quietly piles up.

  1. 1

    Month start — Register your allowance as the monthly budget

    ¥30,000 / month

    Enter your allowance at the start of the month. The app handles the rest.

  2. 2

    Every day — See "how much you can spend today"

    ¥1,000 / day

    Remaining budget ÷ days left = today's safe-to-spend. Stay within it, and money is left over at month-end.

  3. 3

    Unspent money rolls over to tomorrow

    + ¥150 carry-over

    Spent only ¥850 today? Tomorrow you can spend ¥1,150. It feels like a small win, not deprivation.

  4. 4

    Month end — Leftovers auto-deposit to your savings pool

    ¥5,000 → pool

    You don't have to consciously "save" — Yarikuri sweeps the leftover into your savings pool automatically.

¥5,000 leftover × 12 months
= ¥60,000

Keep Step 4 going for a year and this is roughly what builds up.
A trip? A new gadget? A treat for yourself?
